Given:

Maximum load,

P = 50,000 N

Crack length,

a = 3mm

or,

  = 3×10⁻³ m

Diameter,

d = 32 mm

As we know,

⇒  Maximum stress, \(\sigma=\frac{P}{A}\)

                                      \(=\frac{50000}{(\frac{\pi}{4}\times 32^2)}\)

                                      \(=62.20 \ N/mm^2\)

Answer:

Explanation:

(a) The heating requirement for this process is 2.95 x 10⁶ kW

(b) The given benzene analyses are not consistent with each other.

(a) To calculate the heating requirement for this process, we need to determine the heat that must be supplied to the evaporator to vaporize the liquid stream and heat the vapor to the outlet temperature of 95.0°C. We can use the following energy balance:

Q = m(L)v + m(V)h

where Q is the heat required, m(L) and m(V) are the mass flow rates of the liquid and vapor streams, respectively, and v and h are the specific volumes and enthalpies of the liquid and vapor streams, respectively.

To convert the given mole fractions to mass fractions, we need to use the molecular weights of benzene and toluene:

MW_benzene = 78.11 g/mol

MW_toluene = 92.14 g/mol

The mass fraction of benzene in the liquid stream is:

y_B = 0.50

M_B = y_B x MW_benzene / ((1 - y_B) x MW_toluene + y_B x MW_benzene) = 0.436

Similarly, the mass fraction of benzene in the liquid outlet stream is:

x_B = 0.425

M_B = x_B (MW_benzene) / ((1 - x_B)  MW_toluene + x_B ( MW_benzene) = 0.378

And the mass fraction of benzene in the vapor stream is:

z_B = 0.735

M_B = z_B x MW_benzene / ((1 - z_B) x MW_toluene + z_B x MW_benzene) = 0.532

Now we can use Raoult's law to relate the vapor pressures of benzene and toluene in the liquid and vapor streams:

P_B = y_B x P°_B

P_T = (1 - y_B) x P°_T

P'_B = z_B x P°_B'

P'_T = (1 - z_B) x P°_T'

where P°_B and P°_T are the vapor pressures of pure benzene and toluene at 25°C, and P°_B' and P°_T' are the vapor pressures of pure benzene and toluene at 95°C. We can look up these values in a reference table:

P°_B = 12.7 kPa

P°_T = 3.8 kPa

P°_B' = 95.4 kPa

P°_T' = 12.6 kPa

Substituting these values and solving for the vapor pressure of benzene in the liquid and vapor streams, we get:

P_B = 6.35 kPa

P'_B = 50.80 kPa

Now we can calculate the mass flow rates of the liquid and vapor streams:

m(L) = 1320 / (1 + V/L)

m(V) = 1320 - m(L)

where V/L is the ratio of the vapor flow rate to the liquid flow rate, which we can calculate from the vapor-liquid equilibrium relation:

V/L = z_B / (y_B - z_B) = 1.53

Substituting these values and the specific volumes and enthalpies of benzene and toluene, which we can look up in a reference table, we get:

v_L = 0.001319 m³/mol

v_V = 0.03147 m³/mol

h_L = -15702 J/mol

h_V = -11006 J/mol

Q = m(L)v_L(h_V - h_L) + m(V)h_V

Answer:

the reduction in the heat gain is 2.8358 kW

Given that;

Shaft outpower of a motor  = 75 hp = ( 75 × 746 ) = 55950 W

Efficiency of motor  = 91.0% = 0.91

High Efficiency of the motor  = 95.4% = 0.954

now, we know that, efficiency of motor is defined as;  =  /

where   is the electric input given to the motor

so

=  /

we substitute

= 55950 W / 0.91

= 61483.5 W

= 61.4835 kW

now, the electric input given to the motor due to increased efficiency will be;

=  /

we substitute

= 55950 W / 0.954

= 58647.79 W

= 58.6477 kW

so the reduction of the heat gain of the room due to higher efficiency will be;

Q =  -

we substitute

Q = 61.4835 kW - 58.6477 kW

Q = 2.8358 kW

Therefore, the reduction in the heat gain is 2.8358 kW

Explanation:

Given the data in the question;

Vs = 10∠30°V   { peak value }

V"s\(_{rms\) = 10/√2 ∠30° V

resonance freq w₀ = 10³ rad/s

Average Power at resonance Power\(_{avg\)  = 2.5 W

Q = 5

values of R, L, and C = ?

We know that;

Power\(_{avg\) = |V"s\(_{rms\)|² / R

{ resonance circuit is purely resistive }

we substitute

2.5 = (10/√2)² × 1/R

2.5 = 50 × 1/R

R = 50 / 2.5

R = 20Ω

We also know that;

Q = w₀L / R

we substitute

5 = ( 10³ × L ) / 20

5 × 20 = 10³ × L

100 = 10³ × L

L = 100 / 10³

L = 0.1 H

Also;

w₀ = 1 / √LC

square both side

w₀² = 1 / LC

w₀²LC = 1

C = 1 / w₀²L

we substitute

C = 1 / [ (10³)² × 0.1 ]

C = 1 / [ 1000000 × 0.1 ]

C = 1 / [ 100000 ]

C = 0.00001 ≈ 1 × 10⁻⁵ F

The correct statements are 2, 3 and 5. Elastic deformation is a temporary deformation of a material. When a force is applied to a material, it will deform, and the amount of deformation will be proportional to the force applied.

Elastic deformation refers to the reversible deformation of a material when a force is applied and it is released. When the load is removed, the material will return to its original shape. Elastic deformation is characterized by its capability to withstand stress without causing any permanent change in the shape of the material or its molecular structure. The following are the correct statements regarding elastic deformation: Stress and strain are proportional; hence, when stress is applied, the deformation or strain is proportional to the stress. Isostatic uplift following deglaciation represents elastic deformation. This statement is correct. Fold structures are the result of elastic deformation. This statement is correct.

Therefore, If the force is removed, the material will return to its original state. The explanation for elastic deformation is that the stress and strain are proportional, and the deformation will not cause any permanent change in the shape or molecular structure of the material.
