SOLVED PROBLEMS ON AVAILABILITY, IRREVERSIBILITY AND SECOND LAW EFFICIENCY

Problem 3.10

A single stage air turbine is to operate with air inlet pressure and temperature of 1 bar and 600 K. During the expansion, the turbine losses are 20 kJ/kg to the surroundings which is at 1 bar and 300 K. For 1 kg of mass flow rate determine the (i) decrease in availability (ii) maximum work and (iii) irreversibility.

Given data:

p1 = 1 bar

T1 = 600 K

Q = -20 kJ/kg

p2 = 1 bar

T2 = 300 K

m = 1 kg

To find:

ψ1 – ψ2, Wmax and I

Solution:

For any process, the change in entropy,
