1. Find the change in temperature between stations (1) and (2) in terms of the quantities A1, A3, v1, v3, cv, and θ. The internal energy is given by cvT. The fluid is water and T1 =T3, P1 = P3.
2. A liquid flows from A to B in a horizontal pipe line shown at a rate of 3 ft3 /s with a friction loss of 0.45 ft of flowing fluid. For a pressure head at B of 24 in., what will be the pressure head at A?
