THERMODYNAMICS OF FLOW IN TURBO MACHINES Assignment  2 (1)     Air flows through an air turbine where its stagnation pressure is decreased in the ratio of 5:1. The total to total efficiency is 0.8 and the air flow rate is 5 kg/s.. If the total power output is 500 kW, find,(i) Inlet total temperature (ii) The actual exit total temperature (iii) The actual exit static temperature, if the flow velocity is 100 m/s and (iv) the total to static efficiency of the device. (2)     In a centrifugal compressor the air is compressed to double the pressure. The inlet temperature is 27 0 C and the final temperature is 107 0 C. Calculate the efficiency of the compressor and the power required to drive it if 30 kg/min of air is compressed. (3)     Air enters a compressor at a static conditions of 150 kPa and 15 0 C. and a velocity of 50 m/s. At the exit the static conditions are 0.3 MPa and 100 0 C. and a velocity of 100 m/s. Evaluate the isentropi...

MECHANICAL DESIGN – II ASSIGNMENT – 2 A compressor running at 320 rpm is driven by a 50 kW motor running at 1440 rpm through a pair of helical gears. The gears are 20 0 full depth involute in the normal plane and the helix angle is 30 0 . The center distance between the gears is approximately 360 mm. the pinion is to be C30 steel, heat treated and the gear is to be 0.2% carbon steel, untreated. The operation is with medium shock for 8 to 10 hours/day. Design the gear by assuming width of face as 15 times the normal  module A motor shaft rotating at 1400rpm has to transmit 20kW power to a shaft with transmission ratio 3.5 to1 .The teeth are 14.5° involute with 20 teeth on pinion. Both pinion and gear are made of SAE 1040 steel. Design the gears by assuming the starting torque to be 50% higher than the running torque. The pinion is surface hardened to 400H B . Design the pinion  and ...
