1. Calculate the absolute pressure for a system given a guage pressure reading of 1.5
MPa and a barometer (atmospheric pressure) reading of
'- Lﬂﬂiﬁ) A two-phase, liquid—vapor mixture of water, initially at x=3 0% and a pressure
of 100 kPa. is contained in a horizontal piston—cylinder assembly, as shown in the figure.
The mass of the piston is 10 kg, and its diameter is 15 cm. The pressure of
