2. An air-standard regenerative Brayton cycle operates at steady state and produces 10 MW of power Given the pressures and temperatures at the various states in Table 1 below, determine: (a) the specific enthalples (kJ/kg) at all states for which the values are not given, (b) the mass flow rate of air through the cycle in kg/s, (c) the rate of heat transfer (In kW) to the working fluid passing through the combustor, and (d) the thermal efficiency (%) of the cycle. (c) Sketch the cycle on a Ts diagram, showing all states and processes. Assume the compressor and turbine Isentropic efficiencies are both 80% and that the regenerator effectiveness is 70%.
