A rigid tank with a volume of 200 m3 contains 1572 kg of sat

A rigid tank with a volume of 2.00 m^3 contains 15.72 kg of saturated liquid-vapor mixture of water at 75 degree C. Now the water is slowly heated. Determine the temperature at which the liquid in the tank is completely vaporized. Round your answer to the nearest integer. degree C

Solution

we have 15.72 kg of water/steam in an enclosed 2 cu m tank, the specific volume of the saturated vapour must be 2/15.72 = 0.127 cu m/kg.

Next use a \'properties of steam\' table which will tell saturated steam with a volume of 0.127 cu m/kg has a temperature of 201 deg C, and a pressure of more than 16 atmospheres.
