Air enters the compressor of an ideal air-standard Brayton cycle at 80 kPa, 299 K, with a volumetric flow rate of 6.1 m3/s. The compressor pressure ratio is 7. The turbine inlet temperature is 1886 K. Adopting the cold air-standard assumption, calculate: the mass flow rate of air to 3 d.p. in SI unit and privide unit symbol. Take the gas constant as 289 J/kg.K
A water feed pump operates with a mass flow rate of 464 kg/s. The inlet pressure is 689 kPa and the outlet pressure is 26 MPa. Water enters the pump at 422 K. Assuming an isentropic efficiency of 85%, estimate the power required to drive the pump.
On the diagram below sketch a basic Rankine cycle with superheating. Assume that there are irrevesibilities in the turbine and pump. Identify the device associate with each process. Make sure to label: the states and include important features, e.g. lines of constant temperature, volume, pressure, entropy, vapor dome, etc.

Assume a basic (non-regenerative) ideal Brayton cycle where air modeled as IG with variables specific heat. The gas-turbine engine has the following operational parameters: Inlet Air Temperature:537 R Inlet Air Pressure:14.696 psia Compressor Pressure Ratio (rp):6.0 Firing Temperature:2400 R Heat Recovery Steam Generator: Assume that the exhaust from the gas turbine engine is directed to a heat recovery steam generator (HRSG)to produce wet steam (i.e. saturated vapor) at a pressure of 600 psia. Liquid water is supplied to the HRSG at 100F and 600 psia. The exhaust gas from the gas-turbine engine leaves the HRSG at the saturation temperature of the wet steam. With these conditions determine: a) the exit temperature of the wet steam (F), b) the intensive steam production rate, lbm-steam/lbm-exhaust gas. Absorption Chiller CHP: Assume the process steam from the HRSG is now used to drive an absorption chiller with COP of 0.7, and that the mechanical power of the gas-turbine engine is used…
