Answer:

P=7.027psi

V=1.9788ft ^3

Step-by-step explanation:

Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)

through prior knowledge of two other properties such as pressure and temperature.

For the first part of this problem, we must find the water saturation pressure at a temperature of 177F

Psat @(177F)=7.027psi

For the second part of this problem, we calculate the specific volume of the water knowing the temperature and that the state is saturated liquid, then multiply by the mass to know the volume

v@177F=0.01649ft^3/lbm

V=mv

V=(0.01649ft^3/lbm)(120lbm)

V=1.9788ft ^3
