A single-spool turbojet engine is under take- off with compressor pressure ratio of 9 and maximum temperature of 1250 K (To3). The mass flow rate of air entering the engine is 15 kg/s. The ambient conditions are 1 bar and 300 K. The combustion pressure lose is 0.5 bar. Neglect all the other loses and take for air; k = 1.4 and Cpa = 1005 J/(kg.K) and for gas k = 1.333 and Cpg = 1147 J/(kg.K). R = 287 J/(kg.K) for both. The enthalpy of reaction hf = 43100 kJ/kg. Calculate the followings: 1-The stagnation pressure delivered by the compressor (Po2) is ? 2-The stagnation temperature delivered by the compressor (To2)is ? 3-The stagnation pressure of gases entering the turbine (Po3) is ?

pls answer all i will give thumbs up if right
A diesel cycle with air as the working fluid has a compression ratio of 20. The temperature and pressure in the first process is 20°C, 95kPa and the highest attainable temperature is 1927°C. The air standard assumptions are applicable, both Kinetic and Potential energy are negligible. The mass/mass flow rate is negligible. Use the standard constants for air (Cp, Cy. R, and k). Determine the amount of heat transferred and rejected, the net work and thermal efficiency, and the mean effective pressure.
In a Diesel cycle, the volume at the end of the isentropic compression is 0.07 L. If the displaced volume of the cycle is 0.78 L, the cutoff ratio is 1.52, the specific heat ratio is y=1.37 and the heat rejected is 430 kJ/kg, the work done in kj per kg of air is: Select one: a. 705.2 Ob.521.4 Oc. 124.5 d. 566.0
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
