An 90 g aluminum calorimeter contains 390 g of water at an equilibrium temperature of 200C. A 160 g piece of metal, intially at 3050 C, is added to the calorimeter. The final temperature at equilibrium is 320 C. Assume there is no external heat exchange. The specific heat capacities of aluminum and water are 910 and 4190 J/kg. K, respectively. The specific heat capacity of the metal is closest to:

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure. (3.32 mw; 9.69 mw; 4.25 mw; 5.82 mw)
