Question

Water expands through a turbine, and then enters an "unknown" system: The following values are given: P1 = 1 MPa, P2 = 100 kPa, 2: saturated vapor, 3: saturated liquid,

wT = 483.2 kJ/kg For the "unknown" system, the following assumptions are made: w = 0, constant velocity, constant elevation, constant pressure, q out. a) Use general COE to find a simplified expression for the specific heat transfer q in terms of enthalpy values only. Show all your steps. b) Find the value of q, in kJ/kg. What is the change in temperature from 2 → 3? Explain why one of these values is zero while the other is not. c) Find T1, in °C.
