Consider a sealed can that is filled with 4 4 kg of water at 115 C and P 248 kPa Now a leak develops and the pressure in the can drops to the local atmospheric pressure of 100 kPa Cp 4 23 kJ kg K The vapor leaves the can as soon as it is formed How much vapour will evapourate before the liquid water reaches its boiling temperature at atmospheric pressure NB water s enthalpy of vapourisation is roughly 2257 kJ kg a 4 400 kg b 0 120 kg c 1 093 kg d 0 030 kg e 0 015 kg
