5. Steam at 7 bar and 250 °C enters a pipeline and flows along it at constant pressure. If the steam rejects heat steadily to the surroundings, at what temperature will droplets of water begin to form in the vapour? Using the steady-flow energy equation, and neglecting changes in velocity of the steam, calculate the heat rejected per kilogram of steam flowing. (165°C; 191 kJ/kg)

5.
Steam at 7 bar and 250 °C enters a pipeline and flows along it at constant pressure.
If the steam rejects heat steadily to the surroundings, at what temperature will droplets
of water begin to form in the vapour? Using the steady-flow energy equation, and
neglecting changes in velocity of the steam, calculate the heat rejected per kilogram of
steam flowing.
(165 °C; 191 kJ/kg)
6.
0.05 kg of steam at 15 bar is contained in a rigid vessel of volume 0.0076 m'. What
is the temperature of the steam? If the vessel is cooled, at what temperature will the
steam be just dry saturated? Cooling is continued until the pressure in the vessel is
11 bar; calculate the final dryness fraction of the steam, and the heat rejected between
the initial and the final states.
