The mass flow rate of cooling water required is 42.2 kg/s.

To find the mass flow rate of cooling water required, we need to use the energy balance equation. Since the turbine operates adiabatically, there is no heat transfer involved in the turbine.

The energy balance equation for the condenser can be written as:

m°steam * (hin - hout) = m°water * (hout - hin)

Where m°steam is the mass flow rate of steam, hin and hout are the specific enthalpies of the steam at the inlet and outlet of the turbine, respectively. m°water is the mass flow rate of cooling water and hout and hin are the specific enthalpies of the cooling water at the outlet and inlet of the condenser, respectively.

Since the steam exits the turbine as a saturated vapor, its specific enthalpy can be found from the steam tables. At a pressure of 8 kPa, the specific enthalpy of saturated vapor is 2561.5 kJ/kg.

The specific enthalpy of saturated liquid at 8 kPa can also be found from the steam tables, which is 191.81 kJ/kg.

Substituting these values into the energy balance equation, we get:

4.68 * (2561.5 - 191.81) = m°water * (4.18 * (36 - 18))

Solving for m°water, we get:

m°water = 42.2 kg/s

Therefore, the mass flow rate of cooling water required is 42.2 kg/s.

In the case of the production Line, we know that,

No of gasoline cans = 5

probability that 1st can is out of tolerance = 0.03

probability that 2nd can is out of tolerance = 0.03

.

.

probability that the 5th can is out of tolerance = 0.03

Therefore,

probability of 1st can out of tolerance + probability of 1st can not out of tolerance = 1

Probability of 1st can not out of tolerance = 1 -- 0.03 = 0.97

probability of 2nd can not out of tolerance = 0.97

probability of 5th can not out of tolerance = 0.97

Question A:

Probability that they are all out of tolerance

= P(1st can out of tolerance) * P(2nd can out of tolerance) * P(3rd can out of tolerance) * P(4th can out of tolerance) * P(5th can out of tolerance)

Explanation:

The probability, at room temperature, that a state having an energy of 8.540 eV is occupied by an electron in a solid metal with a Fermi energy of 8.500 eV is very low.

The occupation probability of energy states in a solid metal is described by the Fermi-Dirac distribution function. At room temperature, electrons in a solid metal occupy energy states up to the Fermi energy, and the occupation probability decreases rapidly as the energy of the state increases above the Fermi energy.

Since the energy of the state (8.540 eV) is slightly above the Fermi energy (8.500 eV), the probability of an electron occupying this state is very small. This is because at room temperature, most of the available energy states below the Fermi energy are already occupied, and there are very few electrons with enough energy to occupy higher energy states.

The exact calculation of the occupation probability requires the knowledge of temperature and the shape of the density of states function. However, based on the given information and the general behavior of the Fermi-Dirac distribution, we can infer that the probability of an electron occupying a state with an energy of 8.540 eV is expected to be very low at room temperature.

Explanation:

Answer:

The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.

Explanation:

From Heat Transfer we determine that heat transfer rate due to electromagnetic radiation (\(\dot Q\)), measured in BTU per hour, is represented by this formula:

\(\dot Q = \epsilon\cdot A\cdot \sigma \cdot (T_{s}^{4}-T_{b}^{4})\) (1)

Where:

\(\epsilon\) - Emissivity, dimensionless.

\(A\) - Surface area of the student, measured in square feet.

\(\sigma\) - Stefan-Boltzmann constant, measured in BTU per hour-square feet-quartic Rankine.

\(T_{s}\) - Temperature of the student, measured in Rankine.

\(T_{b}\) - Temperature of the bus, measured in Rankine.

If we know that \(\epsilon = 0.90\), \(A = 16.188\,ft^{2}\), \(\sigma = 1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}}\), \(T_{s} = 554.07\,R\) and \(T_{b} = 527.67\,R\), then the heat transfer rate due to electromagnetic radiation is:

\(\dot Q = (0.90)\cdot (16.188\,ft^{2})\cdot \left(1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}} \right)\cdot [(554.07\,R)^{4}-(527.67\,R)^{4}]\)

\(\dot Q = 417.492\,\frac{BTU}{h}\)

Under the consideration of steady heat transfer we find that the net energy transfer from the student's body during the 20 min-ride to school is:

\(Q = \dot Q \cdot \Delta t\) (2)

Where \(\Delta t\) is the heat transfer time, measured in hours.

If we know that \(\dot Q = 417.492\,\frac{BTU}{h}\) and \(\Delta t = \frac{1}{3}\,h\), then the net energy transfer is:

\(Q = \left(417.492\,\frac{BTU}{h} \right)\cdot \left(\frac{1}{3}\,h \right)\)

\(Q = 139.164\,BTU\)

The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.

To find the offset at the PVT (point of vertical tangency) of a 600-ft long equal-tangent vertical curve connecting an initial grade of 1.2% and a final grade of -1.08%, you can use the following formula:

\( \rm \: Offset \: at \: PVT = ( \frac{L}{2} ) \times \frac{(E1 + E2)}{100}\)

Where:

L = Length of the curve = 600 ft

E1 = Initial grade = 1.2%

E2 = Final grade = -1.08%

Substituting the given values into the formula, we get:

\( \rm \: Offset \: at \: PVT = \frac{600}{2} \times \frac{(1.2 - 1.08)}{100}\)

\( \rm \: Offset \: at \: PVT = 300 \times 0.012\)

\( \rm \: Offset \: at \: PVT = 3.6 \: feet\)

Therefore, the offset at the PVT of this vertical curve is 3.6 feet

Answer:

When nitrogen consumption and nitrogen excretion are approximately the same, a person is in nitrogen balance.

Explanation:

In this scenario, we have an aqueous alumina slip containing 45 volume % alumina particles being cast into a gypsum mold. The alumina particles are monodisperse with a size of 1 µm and well-stabilized.

The as-cast layer has a 65% theoretical density, and the gypsum mold has a specific resistance of 2 x 100 cm² and a void fraction of 0.5. The total pressure drop from the slip to the saturation interface in the mold is 0.1 MPa.To plot the cast layer thickness as a function of time, we can utilize Darcy's Law, which governs the flow of a fluid through a porous medium. However, without specific numerical values for the slip's viscosity and the mold's permeability, it is not possible to directly calculate the layer thickness and time relationship.

Nevertheless, to predict the time needed to cast a 1 mm thick layer and the position of the saturation front in the gypsum mold, we would need to perform experiments or numerical simulations based on the given parameters, such as particle size, slip composition, and mold properties. These results could then be used to develop an empirical or theoretical relationship between cast layer thickness and time, enabling accurate predictions for the given conditions.

Both Technician A and Technician B are potentially correct, as both of their suggestions could lead to the HVAC fuse blowing when the A/C switch is turned on.

Given that a HVAC fuse blows each time the A/C switch is turned on, two technicians give their views in that,

Technician A says that an open low-side switch could be the cause. Technician B says that a shorted A/C clutch relay coil could be the cause.
We need to determine which technician is correct,

So, let's look at each possibility:

Technician A: Open Low-Side Switch

The low-side switch in the context of an HVAC system is typically a pressure switch that monitors the refrigerant pressure on the low-pressure side of the A/C system.

If this switch is open (faulty or not closing properly), it may prevent the A/C compressor from engaging, causing an excessive current draw when the A/C switch is turned on.

This excessive current can lead to the HVAC fuse blowing as a protective measure.

Technician B: Shorted A/C Clutch Relay Coil

The A/C clutch relay is responsible for engaging and disengaging the A/C compressor clutch.

If the relay coil is shorted, it may cause a direct connection between the power supply and the A/C compressor clutch, even when the A/C switch is off.

When the A/C switch is turned on, this direct connection could cause a significant current surge, leading to the HVAC fuse blowing to protect the circuit from damage.

In summary, both an open low-side switch and a shorted A/C clutch relay coil can lead to excessive current draw and cause the HVAC fuse to blow.

To determine the exact cause, a thorough inspection and testing of the low-side switch, A/C clutch relay, and associated wiring will be necessary.

It's essential to consult with a qualified automotive technician to diagnose and repair the issue properly.

Hence both the technicians are correct.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.
