A Brayton cycle gas engine is analyzed using the cold air standard method. Given the conditions at state 1, pressure ratio (rp), and cutoff ratio (rc) determine the efficiency and other values listed below. The specific heat ratio and gas constant for air are given as k =1.4 and R=0.287 kJ/kg-K respectively. T1 (K) = 337T2 (K) = 647P1 (kPa) = 169rp = 10.3rc = 1.85AV (m3/s) = 1.4Specific Enthalpy at State 1= 337.396Relative pressure at State 1= 2.0849Relative pressure at State 2= 21.5Required:a. Determine the pressure (kPa) at state 2. b. Determine the temperature (K) at state 3.c. Determine the pressure (kPa) at state 3.d. Determine the specific enthalpy (kJ/kg) at state 3.
