Transcribed Image Text:Question 1 (variation b)
Ten litres (10L) of saturated water steam is contained in a piston-cylinder device and is kept
at 100°C. The piston is frictionless. Nine litres (9 L) of the steam is saturated vapour state, the
rest is in saturated liquid state. The steam then expands under constant pressure until its
temperature reaches 150°C. Calculate:
(a) Total mass of the steam.
(b) The quality of the steam at initial state
(c) The amount of heat required to change the steam from its initial state to the final
state.
(d) Represent the process on a T-v and a P-v diagrams.
