(1) Argon gas expands in a turbine. The exit temperature of the argon for a power output of 190kW is to be determined. Hint: Use ideal gas relationship, cp = 0.5203 kJ/kg.C, R = 0.2081 kPa.m/kg.K A = 60 cm P = 1600 kPa T = 450C V =55 m/s ARGON 190 kW P = 150 kPa V = 150 m/s (2) Steam is condensed by cooling water in the condenser of a power plant. If the temperature rise of the cooling water is not to exceed 10C, the minimum mass flow rate of the cooling water required is to be determined. Mass flow rate of steam is 20'000 kg/hr.
