SOLVED:A power plant operating on heat from a geothermal source uses isobutane as the working medium in a Rankine cycle (Fig. 8.3 ). Isobutane is heated at 3400 kPa (a pressure just a little below its critical pressure) to a temperature of 413.15 K(140^∘ C), at which conditions it enters the turbine. Isentropic expansion in the turbine produces superheated vapor at 450 kPa, which is cooled and condensed to saturated liquid and pumped to the heater/boiler. If the flowrate of isobutane is 75 kg s^
