A blade pair in an axial flow compressor is being designed. The axial flow component of gas velocity is 174m/s. The engine diameter at the mean blade height is 0.73m and the blade height at the rotor inlet is 0.21m. The rotor's absolute inlet flow angle is 26 degrees. The stagnation conditions at the inlet to the blade pair are 298K and 130kN/m² Using Cp 1.005k/kg/K, R-0.287k/kg/K, and taking the ratio of specific heat capacities as 1.4, calculate the engine mass flow rate to the nearest kg/s
Albert bought a portable device to pump his truck tyres. On the manual, he found outthat 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 Dont calculate just indicate formula 1 which formula number will be used to evaluate the induced volume in terms of the swept volume? 2 which formula number will be used to evaluate the mass flow rate of air? 3 which formula number will be used to evaluate the power input to the compressor?

A single stage centrifugal compressor which has an impeller with an overall diameter of 60cm is used in an Auxiliary Power Unit (APU) of an aircraft. The compressor rotates at 12,000 rpm and compresses 29 kg/s of air. The eye inner radius is 64mm and the outer radius is 150mm. If the air inlet temperature and pressure are 280 K and 335 kPa respectively, and there is no pre-swirl or losses in the inlet duct, calculate:(a) the blade inlet angle at root and tip of the eye;(b) the eye tip Mach number;Assuming the slip factor to be 0.9, an isentropic efficiency of 0.85 and the work done factor to be 1.03, calculate:(c) the pressure ratio obtainable;(d) the power required by a turbine to drive the compressor.
