A 440-V, 50-Hz, 4-pole, Y-connected, three-phase induction motor runs at a slip of 5% on full load and develops a power of 10 hp. The slip falls to 2% when the motor is lightly loaded. Determine the torque developed and the power output of the motor when it runs at (a) full load and (b) light load.

How much power could a wind turbine produce if it had the following specifications? cp = 0.45 -d=1.2kg/m3 d=50m v 5m/s

Determine the stoichiometric and actual air-fuel ratios and the mole flue gas composition for combustion with 15% excess air for raw indiana, pennsylvania raw coal.

Air (c-1.006 kj/kg.k, r-0.287 kj/kg.k) enters a nozzle steadily at 280 kpa and 77°c with a velocity of 50 m/s and exits at 85 kpa and 320 m/s. the heat losses from the nozzle to the surrounding medium at 20°c are estimated to be 3.2 kj/kg. determine (a) the exit temperature and (b) the total entropy change for this process. solve this problem using constant specific heats.
