Consider a Carnot engine and the given T-S diagram

Consider a Camot engine and the given T-S diagram.

>> Solution 2.1

As, By Clausius Statement,

dS = Entropy Change = dQ/T = Qh/Th + Q_L/T_L

So, It is True....

>> Solution 2.2

>> As, Carnot Cycle is Reversble and for reversible cycles,

ds = Entropy Chnage = 0

So, Option A is Correct

>> Solution 2.3

>> As, it is Carnot Engine

So, Th/T_L = Qh/Q_L

=> 800/400 = 10/Q_L

=> Q_L = 5 kJ

But as it is extracted out os the system,

=> Q_L = - 5 kJ

>> Solution 2.4

>> As, Work Output, W = Qh - Q_L

=> W = 10 - 5 = 5 kJ .....ANSWER.......OPTION C...
