A rigid Vessel containint initially 100kg of water is going to be heated from 25 degree C to 80 degree C using steam as a medium. the steam will be added slowly such that all the steam condenses. the pressure and temperature conditions of the steam supplied are 3.0 bar and 300 degree C. How many kilograms of steam should be added to reach the desired final temperature of 80 degree C of the tank. You can neglect the heat losses from the tank to perform the calculations
