Albert bought a portable device to pump his truck tyres. On the manual, he found out that the device is a single stage, single-acting air compressor. Air delivery for this device is 30 bar at a speed of 1500 rev/min. The atmospheric condition of his location is 87 kPa and 20 ˚C, with a FAD of 0.22 m2/min. The clearance volume is 4% of theswept volume and the stoke/bore ratio is 1.3/1. Take “n” as 1.3, cp = 1.005 kJ/kg K, cv = 0.718 kJ/kg K Based on pictures below 1 which formula number will be used to evaluate the delivery temperature? 2 which formula number will be used to evaluate the isothermal efficiency? 3 which formula number will be used to evaluate the power input to the compressor?

Air delivery for this device is 30 bar at a speed of 1500 rev/min. The atmospheric condition of his location is 87 kPa and 20 ˚C, with a FAD of 0.22 m2/min. The clearance volume is 4% of theswept volume and the stoke/bore ratio is 1.3/1.
Take “n” as 1.3, cp = 1.005 kJ/kg K, cv = 0.718 kJ/kg K
Based on pictures below
1 which formula number will be used to evaluate the delivery temperature?
2 which formula number will be used to evaluate the isothermal efficiency?
3 which formula number will be used to evaluate the power input to the compressor?
4 which formula number will be used to evaluate the bore and stroke?
