##### Reference no: EM131276646 #### Determine the velocity of the exhaust gases

A turbojet aircraft is flying with a velocity of 280 m/s at an altitude of 9150 m, where the ambient conditions are 32 kPa and 232°C. The pressure ratio across the compresso

#### Determine the amount of heat supplied per cylinder

A four-cylinder spark-ignition engine has a compression ratio of 10.5, and each cylinder has a maximum volume of 0.4 L. At the beginning of the compression process, the air

#### Determine the change in the net work output per unit mass

Consider a simple ideal Brayton cycle with air as the working fluid. The pressure ratio of the cycle is 6, and the minimum and maximum temperatures are 300 and 1300 K, respe

#### Find the net work output per unit mass of air

Consider an ideal Stirling cycle using air as the working fluid. Air is at 400 K and 200 kPa at the beginning of the isothermal compression process, and heat is supplied to

#### Determine the thermal efficiency of this cycle

Determine the thermal efficiency of this cycle as a function of the compressor pressure ratio and the high-pressure turbine to compressor inlet temperature ratio. Compare yo

#### Find the velocity of the gases at the nozzle exit

A turbojet aircraft flies with a velocity of 1100 km/h at an altitude where the air temperature and pressure are -35°C and 40 kPa. Air leaves the diffuser at 50 kPa with a v

#### Find the amount of work produced per cylinder per cycle

Consider a simple ideal Brayton cycle operating between the temperature limits of 300 and 1500 K. Using constant specific heats at room temperature, determine the pressure r

#### Determine the mass flow rates at the two outlets

Determine the mass flow rates at the two outlets (flue gas and fly ash) when 10 kg/s of flue gas and ash mixture enters this unit. Also determine the amount of fly ash colle
