Solve both
A) An inventor claims that a new heat cycle will develop 0.4 kW for a heat
addition of 32.5 kJ/min. The temperature of heat source is 1990 K and that of sink is 850 K. Is
his claim possible ?
B) Steam at a pressure of 5 bar passes into a tank containing water where it
gets condensed. The mass and temperature in the tank before the admission of steam are 50 kg
and 20°C respectively. Calculate the dryness fraction of steam as it enters the tank if 3 kg of
steam gets condensed and resulting temperature of the mixture becomes 40°C. Take water equivalent
of tank as 1.5 kg.
