SOLVED ANNA UNIVERSITY PROBLEMS ON OPEN SYSTEMS FOR UNSTEADY FLOW

AU Problem 1.53

An insulated rigid tank of 1.5 m3 of air with a pressure of 6 bar and 100°C discharges air into the atmosphere which is at 1 bar through a discharge pipe till its pressure becomes 1 bar.

(1) Calculate the velocity of air in the discharge pipe.

(2) Evaluate the work that can be obtained from the frictionless turbine using kinetic energy of that air.

Given data:

Q = 0 (insulated tank)

V1 = V2 = 1.5 m3 (rigid tank)

p1 = 6 bar = 600 kPa

T1 = 100°C = 100 + 273 = 373 K

p2 = 1 bar = 100 kPa
