A tank of volume 0.00354 m3 contains 0.00292 kg of saturated water vapour at 0.143 MPa. A line is attached to the tank in which water vapour flows at 0.7 MPa and 200 C. Steam from this line enters the tank until the pressure in the tank is 0.7 MPa.

i) Why can this process be analysed as uniform flow?

ii) State THREE assumptions, other than uniform flow, that must be made when analysing this process. [3 marks]

iii) Predict and explain what would happen to the temperature of the steam in the tank during this process. [3 marks]
