A Brayton cycle with regeneration and reheat generates 10 MW of power. Air enters the compressor at 100 kPa and 300 K. The compressor operates with a pressure ratio of 12 and an isentropic efficiency of 80%. The air enters the high pressure turbine stage at 1400 K and exits at a pressure of 350 kPa. The air is reheated to 1400 K before entering the second turbine stage. Each turbine stage has an efficiency of 80%. The regenerator has an effectiveness of 80%. Using an air-standard analysis, determine:

a. The pressure and temperature at each state, in kPa and K,

b. The mass flow rate of air, in kg/s,

c. The heat addition rate in kW,

d. The thermal efficiency of the cycle, and

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
