The regenerative Rankine cycle has a number of advantages over the simple Rankine cycle, such as Higher thermal efficiency, Lower exhaust, and Smaller physical size, Shorter startup time.

Higher thermal efficiency as the steam is recycled back to the boiler, resulting in higher efficiency and better fuel economy. Lower exhaust steam pressure and temperature, making it more suitable for applications with lower temperature differences between the heat source and the sink. Shorter startup time as the turbine does not require as much steam to reach operating conditions. Smaller physical size, as the high pressure and temperature equipment, is not necessary.

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 minimum yield strength is approximately 387 MPa (56,120 psi).

A brass alloy for a spring application requiring a modulus of resilience of at least 0.75 MPa (110 psi) needs a certain minimum yield strength. The modulus of resilience is the measure of a material's ability to absorb energy without deforming permanently

It is calculated using the formula: resilience = (yield strength)²/ (2 × elastic modulus). To determine the minimum yield strength, we rearrange the formula as follows: yield strength = √(2 × resilience × elastic modulus).

For brass alloys, the elastic modulus is typically around 100 GPa (14.5 million psi). Using the given resilience of 0.75 MPa, the minimum yield strength is approximately 387 MPa (56,120 psi).

The steel alloy in question contains 93.8 wt% of iron (Fe), 6.0 wt% of nickel (Ni), and 0.2 wt% of carbon (C).

It is assumed that the addition of nickel does not cause any changes in the positions of other phase boundaries within the alloy.

Based on the given composition, the steel alloy consists predominantly of iron (Fe) with a weight percentage of 93.8%. Nickel (Ni) contributes 6.0% by weight, while carbon (C) makes up a minor fraction with 0.2% weight.

Assuming that the addition of nickel does not alter the positions of other phase boundaries within the alloy means that the presence of nickel does not cause significant changes in the microstructure or phase distribution of the alloy. It suggests that the addition of nickel does not introduce new phases or modify the existing phase boundaries.

Therefore, the steel alloy can be considered primarily as an iron-based alloy with a small amount of nickel and carbon. The properties and behavior of the alloy, including mechanical, thermal, and magnetic properties, are likely to be influenced primarily by the iron matrix, while the presence of nickel and carbon may have secondary effects on specific properties, such as corrosion resistance or hardenability.

Answer:

D would be correct because it maximizes it.

The conductors used to connect the surge protection device to the line or bus and to ground shall not be any longer than necessary and shall avoid unnecessary bends.

The length of the conductors should be kept to a minimum to minimize resistance and voltage drop. Unnecessary bends can create impedance and hinder the flow of current. It is important to maintain a direct and efficient path for the electrical current to follow.

By minimizing the length and avoiding unnecessary bends in the conductors, we can ensure that the surge protection device functions optimally and provides effective protection against electrical surges.

We must examine the number of bodies, joints, connectivity, and degrees of freedom of the system in order to calculate the mobility and number of idle degrees of freedom for the mechanisms depicted in Figure 1.

Count the total number of separate stiff bodies or linkages in the mechanism (number of bodies, B).

The total number of joints or connections between the bodies is indicated by the letter J. A point of restriction or relative mobility is represented by each joint.

Total connectivity (C): Add up the degrees of freedom that each joint contributes to determine the total connectivity. The degree of freedom is 1 for simple joints, such as revolute or prismatic joints. The degree of freedom is three for complicated joints, such as spherical or planar joints.

Idle degrees of freedom (IDF): In a system, the idle degrees of freedom are the unnecessary or unrestricted degrees of freedom. It is computed by deducting the system's degrees of freedom from the overall connection.

Mobility (M): Mobility is an indicator of how many independent input parameters are necessary to fully characterise a mechanism's setup. It is determined by subtracting the number of constraints or independent equations from the degrees of freedom.

These elements may be used to calculate the mobility and idle degrees of freedom for the mechanism depicted in Figure 1.

Degree of freedom refers to the number of independent variables or parameters that define the position and orientation of a system. In the context of mechanical systems, degree of freedom represents the number of ways a system can move or be positioned.

In simple terms, degree of freedom can be thought of as the number of independent motions or variables that are required to fully describe the configuration of a system.

For example, consider a rigid body in three-dimensional space. It can have six degrees of freedom, typically represented as three translational degrees of freedom (movement along the x, y, and z axes) and three rotational degrees of freedom (rotation about the x, y, and z axes).

In more complex mechanisms or systems, the degree of freedom can vary based on the number and type of joints, constraints, and the overall structure of the system.

The volume of the activated sludge tank is approximately 0.000142857 m^3/mg VSS, the waste activated sludge flow rate is 0.156 m^3/s, the flow rate of the secondary treated effluent is 0.144 m^3/s, and the hydraulic residence time is approximately 0.000993827 days.

To calculate the volume of the activated sludge tank, we need to use the formula:

Volume = Flow rate / Concentration

Given:

Flow rate of primary effluent (Q) = 0.300 m^3/s

Concentration of mixed liquor (C) = 2,100 mg VSS/L

Volume = 0.300 m^3/s / 2,100 mg VSS/L = 0.000142857 m^3/mg VSS

To find the waste activated sludge flow rate, we use the F/M ratio and the flow rate of primary effluent:

Waste Activated Sludge Flow Rate = F/M * Flow rate

Given:

F/M ratio = 0.52 mg BOD-5/mg VSS^-1 d^-1

Flow rate of primary effluent (Q) = 0.300 m^3/s

Waste Activated Sludge Flow Rate = 0.52 mg BOD-5/mg VSS^-1 d^-1 * 0.300 m^3/s = 0.156 m^3/s

The flow rate of the secondary treated effluent can be calculated by subtracting the waste activated sludge flow rate from the primary effluent flow rate:

Flow rate of secondary treated effluent = Flow rate of primary effluent - Waste Activated Sludge Flow Rate

= 0.300 m^3/s - 0.156 m^3/s = 0.144 m^3/s

To determine the hydraulic residence time, we divide the volume of the activated sludge tank by the flow rate of the secondary treated effluent:

Hydraulic Residence Time = Volume / Flow rate of secondary treated effluent

= 0.000142857 m^3/mg VSS / 0.144 m^3/s = 0.000993827 d

Hence, the volume of the activated sludge tank is approximately 0.000142857 m^3/mg VSS, the waste activated sludge flow rate is 0.156 m^3/s, the flow rate of the secondary treated effluent is 0.144 m^3/s, and the hydraulic residence time is approximately 0.000993827 days.

Answer:

a) it is periodic

N = (20/3)k = 20 { for K =3}

b) it is Non-Periodic.

N = ∞

c) x(n) is periodic

N = LCM ( 5, 20 )

Explanation:

We know that In Discrete time system, complex exponentials and sinusoidal signals are periodic only when ( 2π/w₀) ratio is a rational number.

then the period of the signal is given as

N = ( 2π/w₀)K

k is least integer for which N is also integer

Now, if x(n) = x1(n) + x2(n) and if x1(n) and x2(n) are periodic then x(n) will also be periodic; given N = LCM of N1 and N2

now

a) cos(2π(0.15)n)

w₀ = 2π(0.15)

Now, 2π/w₀ = 2π/2π(0.15) = 1/(0.15) = 1×20 / ( 0.15×20) = 20/3

so, it is periodic

N = (20/3)k = 20 { for K =3}

b) cos(2n);

w₀ = 2

Now, 2π/w₀ = 2π/2) = π

so, it is Non-Periodic.

N = ∞

c)  cos(π0.3n) + cos(π0.4n)

x(n) = x1(n) + x2(n)

x1(n) = cos(π0.3n)

x2(n) =  cos(π0.4n)

so

w₀ = π0.3

2π/w₀  = 2π/π0.3 = 2/0.3 = ( 2×10)/(0.3×10) = 20/3

∴ N1 = 20

AND

w₀ = π0.4

2π/w₀  = 2π/π0. = 2/0.4 = ( 2×10)/(0.4×10) = 20/4 = 5

∴ N² = 5

so, x(n) is periodic

N = LCM ( 5, 20 )

Answer:

- the mass flow rate of air is 7.53 kg/s

- the exit area is 0.108 m²

Explanation:

Given the data in the question;

lets take a look at the steady state energy equation;

m" = W"\(_{cv\) / [ (h₁ - h₂ ) -\(\frac{V_2^2}{2}\) ]

Now at;

T₁ = 900K, h₁ = 932.93 k³/kg

T₂ = 500 K, h₂ = 503.02 k³/kg

so we substitute, in our given values

m" = [ 3200 kW × \(\frac{1\frac{k^3}{s} }{1kW}\) ] / [ (932.93 - 503.02  )k³/kg  -\(\frac{100^2\frac{m^2}{s^2} }{2}\)|\(\frac{ln}{kg\frac{m}{s^2} }\)||\(\frac{1kJ}{10^3N-m}\)| ]

m" = 7.53 kg/s

Therefore, the mass flow rate of air is 7.53 kg/s

now, Exit area A₂ = v₂m" / V₂

we know that; pv = RT

so

A₂ = RT₂m" / P₂V₂

so we substitute

A₂ = {[ \((\frac{8.314}{28.97}\frac{k^3}{kg.K})\)×\(500 K\)×\((7.54 kg/s)\) ] / [(1 bar)(100 m/s )]} |\(\frac{1 bar}{10N/m^2}\)||\(10^3N.m/1k^3\)

A₂ = 0.108 m²

Therefore, the exit area is 0.108 m²
