(a) Illustrate the concept of absolute thermodynamic temperature scale on the basis of second law.
(b) In a Steady flow apparatus , 13.5 KJ of work is done by each kg of fluid. The specific volume of the pressure, fluid, and velocity at inlet are 0.37m3 /kg , 600 KPa and 16 m/s.The inlet is 32m above the floor , and the discharge pipe is at floor level. The discharge conditions are 0.62m3 /kg, 100 KPa and 270 m/s . The net heat loss between the inlet and discharge is 9KJ/Kg of fluid. In flowing through this apparatus , does the specific internal energy decrease or increase and by how much?
