Find the temperature of the following using the ideal gas law:
(a) water, P=10KPa, v=30m^3/kg
(b) water, P=10MPa, v=0.019m^3/kg

Step 1

According to question we have to use ideal gas law, but the parameters are given for water. we cannot apply ideal gas equation for water as water is incompressible fluid or the condition of water changes with pressure and temperature. Even we cannot take steam as an ideal gas that will give error of about 5 to 10% or more. Hence, we find the value of temperature of water with the help of steam table.

Step 2

Part (a):

Given:

P=10KPa = 0.01MPa

v=30m3/kg

from the steam table of superhea...
