Solved Anna University Problem on Clausius Inequality: Second Law and Entropy - Engineering Thermodynamics

SOLVED ANNA UNIVERSITY PROBLEM ON CLAUSIUS INEQUALITY

AU Problem 2.32

An inventor claims to have developed an engine which receives 1000 kJ at a temperature of 160°C. It rejects heat at a temperature of 5°C and delivers 0.12 kWh of mechanical work. Is this a valid claim? Justify your answer through Classius inequality.

Given data:

Q1 = 1000 kJ

T1 = 160°C = 160 + 273 = 433 K

T2 = 5°C = 5 + 273 = 278 K

W = 0.12 kWh = 0.12 × 3600 = 432 kJ

To find:

Check for validity of claim.
