For each of the cases below, determine if the heat engine satisfies the first law (energy equation) and if it violates the secon

stepan [7]

Answer:

From first law of thermodynamics(energy conservation)

Qa= Qr+W

Qa=Heat added to the engine

Qr=heat rejected from the engine

W=work output from the engine

Second law:

It is impossible to construct a heat engine that will deliver the work with out rejecting heat.

In other word ,if engine take heat then it will reject some amount heat and will deliver some amount of work.

1.

QH=6 kW,

QL=4 kW,

W=2 kW

6 KW= 4 + 2 KW

It satisfy the first law.

Here heat is also rejected from the engine that is why it satisfy second law.

2.

QH=6 kW, QL=0 kW, W=6 kW

This satisfy first law but does not satisfy second law because heat rejection is zero.

3.

QH=6 kW , QL=2 kW, W=5 kW

This does not satisfy first as well as second law.Because summation of heat rejection and work can not be greater than heat addition or we can say that energy is not conserve.

4.

QH=6 kW, QL=6 kW, W=0 kW

This satisfy first law only and does not satisfy second law.

Consider an open loop 1-degree-of-freedom mass-spring damper system. The system has mass 4.2 kg, and spring stiffness of 85.9 N/

Marat540 [252]

Answer:

Damping ratio $\zeta =0.0342$

Explanation:

Given that

m=4.2 kg,K=85.9 N/m,C=1.3 N.s/m

We need to find damping ratio

We know that critical damping co-efficient

$C_c=2\sqrt {mk}$

$C_c=2\sqrt {4.2\times 85.9}$

$C_c=37.98$ N.s/m

Damping ratio( $\zeta$ ) is the ratio of damping co-efficient to the critical damping co-efficient

So $\zeta =\dfrac{C}{C_c}$

$\zeta =\dfrac{1.3}{37.98}$

$\zeta =0.0342$

So damping ratio $\zeta =0.0342$

1. When the pneumatic device was demonstrated, explain something that was different than what you expected.

Vera_Pavlovna [14]

Answer:

1. Effect of air pressure

2. air- powered wheel chair

3. Pneumatic valves

Explanation:

1. In any pneumatic device, the mipact of air pressure to produce the moving effect on an heavy object is unexpected.

2. pneumatice demultiplexer when air in comprressed tank is allowed released to cause movement of the chair.

3. In industries, a pneumatic valve operates by force of air when actuated. A signal causes actuation of coil. When coil is energized, compressed high pressure air is allowe to enter in a small cylinder and cause operation of valve
