The sections of piping immediately upstream and downstream of a primary flow measuring device are known as the "straight run."

The straight run refers to the lengths of piping that are required to be present immediately upstream and downstream of a primary flow measuring device. These sections of piping are necessary to ensure that the flow profile is fully developed and unaffected by any disturbances caused by bends, fittings, or obstructions in the pipe. The straight run allows the fluid to flow smoothly and uniformly before entering or exiting the flow measuring device, ensuring accurate and reliable measurements.

By providing sufficient straight run lengths, the flow profile becomes stable, minimizing turbulence and disturbances that could impact the accuracy of the flow measurement.

At 1.2mpa pressure and 50c

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg

(COP)r = 238/53
(Cop) = 4.490

Therefore the above values are the (a) mass flow rate of the refrigerant, b) the refrigerant load, c) the cop, and d) the minimum power input to the compressor for the same refrigeration load.

The current that passes through the residual heater is 4.94 Ampere.

Given,

         Volume = 0.3 m³

         Pressure = 200 kPa

         Temperature = 27°C

         Voltage = 110 V

         Time = 10 minutes

According to the ideal gas equation,

m = PV/RT = 200×10³×0.3/(189×(27+273)) = 1.058 kg

V₁/T₁ = V₂/T₂

T₂ = (V₂/V₂)×T₁ = 2×(27+273) = 600 K = 600 - 273 = 327°C

W = P(V₂ - V₁) = 200×10³ ×(2×0.3 - 0.3) = 60 kJ

Q - W = mCp(T₂ - T₁)

Q - 60 = 1.058×0.839×(327-27)

Q = 326.3 kJ

V×I×t = 326.3 kJ

110×I×(10×60) = 326.3×10³

Current I = 4.94 A

Thus, the current that passes through the residual heater is 4.94 A.

Answer:

Final mass of Argon=  2.46 kg

Explanation:

Initial mass of Argon gas ( M1 ) = 4 kg

P1 = 450 kPa

T1 = 30°C = 303 K

P2 = 200 kPa

k ( specific heat ratio of Argon ) = 1.667

assuming a reversible adiabatic process

Calculate the value of the M2

Applying ideal gas equation ( PV = mRT )

P₁V / P₂V = m₁ RT₁ / m₂ RT₂

hence : m2 = P₂T₁ / P₁T₂ * m₁

                   = (200 * 303 ) / (450 * 219 ) * 4

                   = 2.46 kg

A PRIMARY KEY that consists of more than one column is called a composite key.

The column or columns that each row in a database uses to uniquely identify itself is known as the primary key. For Optim to insert, update, restore, or remove data from a database table, the table must contain a primary key. The primary keys set for the database are used by Optim.

In a relational database management system (RDBMS), such as an Oracle database or SQL server, a primary key has a specific function inside the data table. A primary key should be based on a single attribute or a collection of attributes for each object in a data model.

The major function of a primary key is to determine a row's uniqueness, whereas the primary function of a unique key is to avoid duplication. The fundamental differences between primary keys and unique keys are as follows. A table can only have one primary key, which is known as a primary key. One or more columns make up the main key.

Explanation:

Total heat rejected by compressor = Heat rejected by compression + Heat rejected by intercooler

Heat rejected by compression :

Q = (y - n)/(y - 1) • W

Q = (y - n)/(y - 1) • R(T2 - T1)/(n - 1) ... (i)

Heat rejected by intercooler :

Q = Cp(T2 - T1) ... (ii)

Sum of (i) and (ii) :

Q = (i) + (ii)

Q = (y - n)/(y - 1) • R(T2 - T1)/(n - 1) + Cp(T2 - T1) ... (iii)

Remember that :

R = Cp - Cv

y = Cp/Cv

So :

R = yCv - Cv

R = Cv(y - 1) ... (iv)

Now, subtitute (iv) to (iii) :

Q = (y - n)/(y - 1) • Cv(y - 1)(T2 - T1)/(n - 1) + Cp(T2 - T1)

Q = (y - n)/(n - 1) • Cv(T2 - T1) + Cp(T2 - T1)

Q = [Cp + Cv • (y - n)/(n - 1)] • (T2 - T1)

Complete Question is attached below.

Answer:

\(V'=5m/s\)

Explanation:

From the question we are told that:

Diameter \(d=0.10m\)

Power \(P=4.0kW\)

Head loss \(\mu=10m\)

 \(\frac{P_1}{\rho g}+\frac{V_1^2}{2g}+Z_1+H_m=\frac{P_2}{\rho g}+\frac{V_2^2}{2g}+Z_2+\mu\)

 \(\frac{300*10^3}{\rho g}+35+Hm=\frac{500*10^3}{\rho g}+15+10\)

 \(H_m=(\frac{200*10^3}{1000*9.8}-10)\)

 \(H_m=10.39m\)

Generally the equation for Power is mathematically given by

 \(P=\rho gQH_m\)

Therefore

 \(Q=\frac{P}{\rho g H_m}\)

 \(Q=\frac{4*10^4}{1000*9.81*10.9}\)

 \(Q=0.03935m^3/sec\)

Since

 \(Q=AV'\)

Where

 \(A=\pi r^2\\A=3.142 (0.05)^2\)

 \(A=7.85*10^{-3}\)

Therefore

 \(V'=\frac{0.03935m^3/sec}{7.85*10^{-3}}\)

The correct option is (c) causes the aircraft to be used or authorizes its use. Regulations that relate to operate refer to the person who causes the aircraft to be used or authorizes its use.

Regulations that relate to operate mean that the person who causes the aircraft to be used or authorizes its use is responsible. Regulations are legal standards set by government authorities to provide guidance, protection, and safety to citizens.

For example, the Federal Aviation Administration (FAA) is responsible for setting regulations governing aircraft operation.

The pilot in command (PIC) is the pilot responsible for flying an aircraft during a flight operation. A PIC must have the legal authority and responsibility for the flight. They are responsible for the aircraft and crew, and must ensure that the flight is conducted safely in compliance with regulations.

As a result, the regulations that relate to operate do not apply to the pilot in command or the sole manipulator of the aircraft controls.

The iron triangle concept suggests that policy creation involves a close relationship between bureaucratic agencies, interest groups, and congressional committees, leading to a stable and resistant policy framework.

The iron triangle concept supports the view that policy creation is heavily influenced by a close relationship between three entities: bureaucratic agencies, interest groups, and congressional committees. This concept suggests that these three entities form a mutually beneficial relationship where each party provides support and benefits to the others.

Bureaucratic agencies implement and enforce policies, interest groups advocate for specific policies, and congressional committees oversee policy development and provide legislative support. The iron triangle concept implies that these three entities work together to shape and maintain policies, often resulting in a stable and resistant policy framework that can be challenging to change or reform.
