ANSWER:Step 1 of 8
Part (a)
Consider the properties at from the saturated water (liquid-vapor).
Specific volume of saturated liquid,
Specific volume of saturated vapor,
Saturated pressure,
The given specific volume lies between the value of specific volume of saturated liquid and vapor .therefore the pressure is .
Therefore, from the table A-2,
Hence the temperature in is .
