A 0.6-m3 rigid tank is filled with saturated liquid water at 170 °C. A valve at the bottom of the tank is now opened, and one- half of the total mass is withdrawn from the tank in liquid form. Heat is transferred to water from a source of 210 °C so that the temperature in the tank remains constant. Determine (a) the amount of heat transfer and (b) the reversible work and exergy destruction for this process. Assume the surroundings to be at 25 °C and 100 kPa.
