Refrigerant-22
in a non-insulated piston cylinder arrangement is initially at 52
°C and x = 1
(saturated vapor). It is then expanded to a pressure of 100 kPa in a
process so that at all times
P =
A * (v-1),
where P [=] kPA, v [=] m3,
A [=] kPa*m3
where
A is a constant. The total mass of the system is M kg.
