Consider the ideal Stirling cycle shown above, working between a
maximum temperature of 770 K and a minimum temperature of 420 K and
a minimum volume of 0.3 L and a maximum volume of 1.2 L. The
working gas of the cycle is 0.10 mol of an ideal gas with
c′v = 20.8 J/mol-K.
Note, +Q = heat absorbed by the gas and +W = work done
by the gas.

A compressor works on a pressure of 105 kPa and temperature 300 K in a Brayton cycle and has an efficiency of 45%. The exhaust temperature is 700 K. Find the pressure ratio and the specific heat addition by the combustion for this cycle. The inlet pressure of an air compressor is 100 kPa, with temperature 290 K, and brings it to 600 kPa, after which the air is cooled in an intercooler to 330K by heat transfer to the...

3. Exhaust Velocity A jet engine that operates on Brayton cycle is at an altitude (30,000 ft) where the engine entrance temperature is 228 K and the pressure is 30.8 kPa. We also know that the engine compressor pressure ratio is rp= 10 and the fuel to air mass flowrate ratio is 0.03. If the aircraft is moving at a velocity of 305 m/s and uses fuel with LHV 44,102 kJ/kg calculate the engine exhaust velocity. (Note that cp 1.0035...
