Consider a combined gas-steam power cycle. the topping cycle is a simple brayton cycle that has a pressure ratio of 7. air enters the compressor at15°c at a rate of 10 kg/s and the gas turbine at 950°c. the bottoming cycle is a reheat rankine cycle between the pressure limits of 6 mpa and 10 kpa. steam is heated in a heat exchanger at a rate of 1.15 kg/s by the exhaust gases leaving the gas turbine and the exhaust gases leave the heat exchanger at 200°c. steam leaves the high-pressure turbine at 1.0 mpa and is reheated to 400°c in the heat exchanger before it expands in the low-pressure turbine. assuming 80 percent isentropic efficiency for all pumps and turbine, determine (a) the moisture content at the exit of the low-pressure turbine, % (b) the steam temperature at the inlet of the high-pressure turbine, °c (c) the net power output and the thermal efficiency of the combined plant. w kw %

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
