a pressure cooker cooks a lot faster than an ordinary pan by maintaining a higher pressure and temperature inside. the lid of the pressure cooker is well sealed, and steam can escape only through an opening in the middle of the lid. a separate piece of certain mass, the petcock, sits on top of this opening and prevents steam from escaping until the pressure force overcomes the weight of the petcock, forcing it to rock and releasing steam. the periodic escape of the steam in this manner prevents only potentially dangerous pressure buildup and keeps the pressure inside at a constant value. determine the mass of the petcock of a pressure cooker whose operation pressure is 100 kpa gage and has an opening cross-sectional area of 5 mm2 . assume an atmospheric pressure of 101 kpa

In case 1, the two loops are placed perpendicular to the current-carrying wire. This is done to measure the magnetic field produced by the wire. When a current flows through a wire, it produces a magnetic field around it. The magnetic field is perpendicular to the direction of the current flow.

By placing the two loops perpendicular to the wire, they intercept the magnetic field lines produced by the wire. The changing magnetic field induces an electric current in the loops, which can be measured and used to determine the strength of the magnetic field. In case 2, the two loops are placed parallel to the current-carrying wire. This configuration is used to measure the current flowing through the wire. When the current flows through the wire, it produces a magnetic field around it.

The magnetic field lines encircle the wire and pass through the two loops. As the magnetic field changes, it induces an electric current in the loops. The induced current is proportional to the current flowing through the wire. By measuring the induced current, the current flowing through the wire can be determined. In both cases, the two loops are placed in close proximity to the current-carrying wire to ensure maximum interaction with the magnetic field. Additionally, the loops are made of a conductive material such as copper, which allows for the induction of an electric current when exposed to a changing magnetic field.

The capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.

A DC series circuit can be defined as a type of circuit in which all of its resistive components are connected end to end, so as to form a single path for the flow of current.

This ultimately implies that, the same amount of current flows through a direct current (DC) series circuit.

Mathematically, the capacitive reactance of a DC series circuit is given by this formula:

\(X_C = \frac{1}{2\pi fC}\)

Where:

From the above formula, we can deduce that the capacitive reactance of a DC series circuit is inversely proportional to both frequency and capacitance. Thus, the capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.

Answer:

The inlet velocity v₁ = 6.66 m/s, the exit velocity v₂ = 7.32 m/s and the volume flow rate Q = 4.72 m³/s

Explanation:

Using Bernoulli's equation

P₁ + ρgh₁ + 1/2ρv₁² = P₂ + ρgh₂ + 1/2ρv₂²

P₁ - P₂ + ρgh₁ -  ρgh₂ = 1/2ρv₂² - 1/2ρv₁²

ΔP + ρgΔh = 1/2ρ(v₂² - v₁²)  (1)

where ΔP = pressure difference = 12.35 kPa = 12350 Pa

Δh = height difference = 1.35 m

From the flow rate equation Q = A₁v₁ = A₂v₂ and v₁ = A₂v₂/A₁ = d₂²v₂/d₁² where v₁ and v₂ represent the inlet and exit velocities from the pipe and d₁ = 0.95 m and d₂ = 0.44 m represent the diameters at the top end and lower end of the pipe respectively.

Substituting v₁ into (1), we have

ΔP + ρgΔh = 1/2ρ(v₂² - (d₂²v₂/d₁² )²)

ΔP + ρgΔh = 1/2ρ(v₂² - (d₂/d₁)⁴v₂²)

v₂ = √[2(ΔP + ρgΔh)/ρ(1 - (d₂/d₁)⁴)}

substituting the values of the variables, we have

v₂ = √[2(12350 Pa + 1000 kg/m³ × 9.8 m/s² × 1.35 m)/(1000 kg/m³ (1 - (0.44 m/0.95 m)⁴))}

= √[2(12350 Pa + 13230 Pa)/(1000 kg/m³ × 0.954)]

= √[2(25580 Pa)/954 kg/m³]

= √[51160 Pa/954 kg/m³]

= √53.627

= 7.32 m/s

v₁ = d₂²v₂/d₁²

  = (0.44 m/0.95 m)² × 7.32 m/s

  = (0.954)² × 7.32 m/s

  = 6.66 m/s

The volume flow rate Q = A₁v₁

= πd₁²v₁/4

= π(0.95 m)² × 6.66 m/s ÷ 4

= 18.883 m³/s ÷ 4

= 4.72 m³/s

So, the inlet velocity v₁ = 6.66 m/s, the exit velocity v₂ = 7.32 m/s and the volume flow rate Q = 4.72 m³/s

In the given problem, the corresponding range of saturated unit weight (γsat) for the sandy soil is 13.54 kN/m³ to 18.92 kN/m³.

To decide the range of saturated part weight (γsat) for the sandy soil, we need to form a few presumption and use relevant equatings. Here's how we can approach this question:

Assumptions:

Furthermore, the equation that relates the universe ratio (e) and saturated part weight (γlie) of a soil can be given as: γsat = (1+e) * γw

where: γw is the unit weight of water (assumed to be 9.81 kN/m³).

Given the following:

Minimum void ratio (e) = 0.38

Maximum void ratio (e) = 0.92

Unit weight of water (γw) = 9.81 kN/m³

We can solve below:

Using the equation above, we can solve the minimum and maximum γsat values:

Minimum γsat = (1 + 0.38) * 9.81 = 1.38 * 9.81 = 13.54 kN/m³

Maximum γsat = (1 + 0.92) * 9.81 = 1.92 * 9.81 = 18.92 kN/m³

Part B

The weight of water to be added is approximately 19886.\(\overline{36}\) kN, the volume of the water added is approximately 2,027.77 m³

Explanation:

The parameters of the soil are;

The volume of sol the excavator excavates, \(V_T\) = 10,000 m³

The moist unit weight, W = 17.5 kN/m³

The moisture content = 10%

The area of the project, A = 20,000 m²

The required dry unit weight = 18.3 kN/m³

The required moisture content = 12.5%

Part A

Therefore, we have;

The moist unit weight = Unit weight = (\(W_s\) + \(W_w\))/\(V_T\)

The moisture content, MC = 10% = (\(W_w\)/\(W_s\)) × 100

∴ \(W_w\) = 0.1·\(W_s\)

∴ The moist unit weight = 17.5 kN/m³ = (\(W_s\) + 0.1·\(W_s\))/(10,000 m³)

1.1·\(W_s\) = 10,000 m³ × 17.5 kN/m³ = 175,000 kN

\(W_s\) = 175,000 kN/1.1 = 159,090.\(\overline{09}\) kN

For the required soil, we have;

The required dry unit weight = 18.3 kN/m³ = \(W_s\)/\(V_T\) = 159,090.\(\overline{09}\) kN/\(V_T\)

\(V_T\) = 159,090.\(\overline{09}\) kN/(18.3 kN/m³) ≈ 8,693.4923 m³

The total volume of the required soil ≈ 8,693.4923 m³

Volume \(V_T\) = Area, A × Thickness, d

∴ d =  \(V_T\)/A

d = 8,693.4923 m³/(20,000 m²) ≈ 4.3467 × 10⁻¹ m

The thickness of the compacted soil ≈ 4.3467 × 10⁻¹ m

Part A

The moisture content, MC = 12.5% = (\(W_w\)/\(W_s\)) × 100

\(W_w\) = \(W_s\) × MC/100 = 159,090.\(\overline{09}\) kN × 12.5/100 = 19886.\(\overline{36}\) kN

The weight of water to be added, \(W_w\) = 19886.\(\overline{36}\) kN

Where the density of water, ρ = 9.807 kN/m³

Therefore, we have;

The volume of water, V = \(W_w\)/ρ

∴ V = 19886.\(\overline{36}\) kN/(9.807 kN/m³) ≈ 2027.77 m³

The volume of water, V ≈ 2027.77 m³
