A plane is powered by a turbojet engine where atmospheric conditions are

A plane is powered by a turbojet engine where atmospheric conditions are To = 232 K, Po = 60kPa. Temperature before the turbine is T4 = 1300K and the flight speed is 700km/h. Mass flow rate of fuel is 0,13 kg/sec. Assume total mass flow rate is equal to ma+mf, ne = 0,98, T=12, CV=44 MJ/kg, k=1,4, R=287 J/kg K. assume Cpc = CpT = Cp and inlet pressure loss coefficient is 0,95. Calculations should be done for total parameters. Calculate: . Tro. Pro Trz, Prz Trari Pra ma Power delivered to the compressor (le)
