Bourdon Tube gauge
Explanation:
The most popular type of pressure gauge in several countries is the Bourdon pressure tube gauge, that is used to determine medium and high loads. Bourdon tube will measure pressures ranging between 600 mbar - 4,000 bar. While the inner pressure is greater than the exterior pressure, the tube pushes forward, and vise versa.
technician a says that the upper shell of a main bearing is identified by a marking on the back of the shell. technician b says that the upper main bearing shell will always have a hole in it. who is correct?
Technician b is correct that he says affirms that the top main bearing shell will always be pierced by a hole.
A housing, shaft, and lubricant are other parts of the system, which also contains a bearing shell. As a result, they must be developed in concert with the bearing shell as a part of a bearing system as the dependability of the bearing shells is dependent on these other components. Their main objective is to make this rotation of the components almost wear-free. Plain bearings consist of one or two bearing shells that are tightly secured within the bearing seat. The spinning shaft is encircled by the bearing shells at the bearing journals. A steel alloy shell serves as the foundation for every bearing insert, upon which the softer bearing componentsis connected. Bearings may currently be divided into two main categories: those made of aluminum alloy or copper/lead alloy.

A fluid of density 880 kg/m' and viscosity 0.32 N.s/m® flows steadily down through a 0.15 m diameter vertical pipe and comes out as a free jet from the lower end. Determine the maximum pressure in the pipe at point 4.75 m vertically above the exit such that flow just remains laminar. (-30.00 kPa]
Maximum pressure: -30.00 kPa (below atmospheric).
How to determine maximum pressure?To determine the maximum pressure in the pipe at a specific point, we can use the concept of Bernoulli's equation for steady, incompressible flow. Bernoulli's equation states that the sum of pressure, kinetic energy per unit volume, and potential energy per unit volume remains constant along a streamline.
In this case, the flow is laminar, and we need to find the maximum pressure at a point 4.75 m vertically above the exit. Since the flow is steady, the pressure at this point can be determined using Bernoulli's equation by considering the pressure, velocity, and height of the fluid.
Bernoulli's equation can be expressed as:
P1 + 0.5ρ\(v1^2\) + ρgh1 = P2 + 0.5ρ\(v2^2\) + ρgh2
Here, P1 is the pressure at the exit, v1 is the velocity at the exit, h1 is the height at the exit, P2 is the pressure at the point of interest, v2 is the velocity at the point of interest, and h2 is the height at the point of interest.
Given the fluid density ρ = 880 kg/\(m^3\), the viscosity η = 0.32 N.s/\(m^2\), and the diameter of the pipe d = 0.15 m, we can calculate the velocity at the exit using the principle of continuity, which states that the flow rate is constant along a streamline. For a steady, incompressible flow, the flow rate can be expressed as A1v1 = A2v2, where A1 and A2 are the cross-sectional areas at the exit and the point of interest, respectively.
By substituting the known values and solving Bernoulli's equation, we can determine the maximum pressure at the point 4.75 m vertically above the exit.
The calculated maximum pressure is -30.00 kPa, indicating that the pressure at the given point is below atmospheric pressure

Water enters a vertical jet with low velocity and a pressure of 350 kPa. What is the maximum height that the water can rise above the jet
The maximum height that the water can rise above the jet is: 35 meters.
Maximum height that the water can rise above the jetGiven:
P = 350 kPa = 350000 Pa
We would use pressure(p) formula to determine the maximum height that the water can rises above the jet by solving for h (height).
Using this formula
Pressure(P) = P₀ + ρgh
Where;
P₀ represent Pressure at the fluid's surface
ρ represent Density of the fluid = 1000 kg/m³
g represent acceleration due to gravity = 10 m/s².
h represent height
Solving for h (height)
350000 = 0 + (1000 × 10 ×h)
350000 = 10000h
Divide both side by 10000h
h = 350000/10000
h = 35 meters
Therefore the maximum height that the water can rise above the jet is: 35 meters.

A commercial jet is flying at a standard altitude of 35,000 ft with a velocity of 550 mph: (a) what is the Mach number? (b) should the flow be treated as incompressible, why or why not?
Answer:
Mach number = 0.68168
The flow should be treated as compressible.
Explanation:
Given that:
The altitude of a commercial jet = 35000
The properties of air at that given altitude are as follows:
Pressure = 24.577 kPa
Temperature T = 50.78176° C
Temperature T = ( 50.78176 + 273 )K = 328.78176 K
\(\varphi = 0.38428 \ kg/m^3\)
The velocity is also given as: 550 mph = 245.872 m/s
Therefore, the sonic velocity is firstly determined by using the formula:
\(a = \sqrt{ \vartheta \times R \times T\\)
\(a = \sqrt{1.4 \times 287 \times 323.78176\)
\(a = \sqrt{130095.5112\)
a = 360.68755 m/s
Then, we can calculate the Mach number by using the expression:
\({Mach \ number = \dfrac{V}{a}}\)
\(Mach \ number = \dfrac{245.872}{360.68755}\)
Mach number = 0.68168
b) Ideally, all flows are compressible because the Mach number is greater than 0.3, suppose the Mach number is lesser than 0.3, then it is incompressible.

What is the governing design strength of the connection?
Calculating the design strength of a connection involving a tension member, channel member, and gusset plate, considering bolt shear failure and bearing failure in both the channel member and the gusset plate.
To calculate the design strength of the connection, we need to consider bolt shear failure, bearing failure in the channel member, and bearing failure in the gusset plate. The C8x18.75 channel member is bolted to a 3/8 in. thick gusset plate with 5/8 in. diameter A325 bolts. The tension member is A572 Grade 50 steel, and the gusset plate is A36 steel. We assume that threads are included in the shear plane.
The design strength is calculated using the nominal strengths of the bolts and the bearing strengths of the channel member and gusset plate. The governing strength is the minimum of the three.
The calculations show that 14 bolts are needed to resist the tensile force on the member if bolt shear failure governs. If bearing failure in the channel member governs, 11 bolts are required, and if bearing failure in the gusset plate governs, 13 bolts are needed. Therefore, bearing failure in the channel member governs, and the design strength of the connection is 312.4 kips.
All the edge distance and spacing requirements are satisfied. The calculations assume that threads are included in the shear plane, and the hole diameter is 11/16 in. The design strength of the connection is limited by bearing failure in the channel member.

The less expensive motor has an initial purchase cost of $1000 and is 88% efficient. The more expensive motor has an initial purchase cost of $1500 and is 92% efficient. The plant pays $0.07/kW⋅h, which reflects the cost if the total electricity costs are paid at the end of year 10 . The annual effective interest rate over a 10 -year period of life is 10%. If both options have the same net present worth and the same operating time per year, what is most nearly the operating time per year? (A) 250 h/yr (B) 400 h/yr (C) 690 h/yr (D) 720 h/yr
We are required to determine the operating time per year in the given case. Here's how we can solve this problem:A plant engineer is evaluating the purchase of two possible motors.
Both motors are each rated at 125hp, but have different efficiencies and purchase costs. The less expensive motor has an initial purchase cost of $1000 and is 88% efficient. The more expensive motor has an initial purchase cost of $1500 and is 92% efficient.
The plant pays
$0.07/kW⋅h,
which reflects the cost if the total electricity costs are paid at the end of year 10. The annual effective interest rate over a 10-year period of life is 10%.The net present value (NPV) formula to compare two different options of investment (purchase of a motor in this case) is
NPV = C1 + C2/(1+i)² + C3/(1+i)³ + ….. - CI/(1+i)n
where,Ci = Cash inflow/outflow for year i (year 0 is usually the present year)
i = Discount rate
N = life of the investment
As both the options have the same net present value, we can assume that the net present value for both the options would be equal.
Calculating the net present value of Option 1 (Less expensive motor):Initial purchase cost
= $1000Operating cost (electricity)
= (125hp × 0.746 kW/hp) × (1/0.88 - 1) × 365 × 24 h/yr × $0.07/kWh =$6158.01
Net Present Value of Option
1 = -$1000 - $6158.01/(1+0.10)²
= -$4641.63
Calculating the net present value of Option 2 (More expensive motor):Initial purchase cost
= $1500O
perating cost (electricity)
= (125hp × 0.746 kW/hp) × (1/0.92 - 1) × 365 × 24 h/yr × $0.07/kWh
= $5337.69Net Present Value of Option 2
= -$1500 - $5337.69/(1+0.10)² = -$4665.
14Now we can use the following equation:Operating time per year
= (annual electricity cost)/(125hp × 0.746 kW/hp × (1/η - 1))where,η
= Efficiency of the motorUsing the above equation for both the options, we get:Operating time per year for Option 1
= $6158.01/(125hp × 0.746 kW/hp × (1/0.88 - 1))
= 614.36 h/yrOperating time per year for Option 2
= $5337.69/(125hp × 0.746 kW/hp × (1/0.92 - 1))
= 690.47 h/yr
Therefore, the most nearly operating time per year is (C) 690 h/yr.
