What are the four steps in a Carnot's engine?

Assuming that the working substance of a carnot's engine is a perfect gas show that the ratio of heat rejected at the sink to that extracted from the source equals the ratio of absolute temperature of the sink and the source .

What are the main steps in aerobic respiration? Where does it take place?

Why is the efficiency of a carnot's engine not 100%?

The temperature of source and sink of a carnot engine are 400K and 300k respectively its efficiecy is

State Carnot's principle

What are the steps involved in formation of a root nodule?

Describe the various operation of a carnot's reversible engine and obtain and expression its efficiency .

Write the expression of efficency of Carnot engine.

What is carnot's theorem .

To maintain a rotor at a uniform angular speed of 200 rad s~ 1, an engine needs to transmit a torque of 180 Nm. What is the power required by the engine? (Note: uniform angular velocity in the absence of friction implies zero torque. in practice, applied torque is needed to counter frictional torque). Assume that the engine is 100 % efficient.
