A gas turbine takes in 250,000 lbm/hr of air at 80f and compresses it to 6 atmospheres. the combustion of gas adds 100x10^6 Btu/hr of heat to the air. The turbine exhausts to atmospheric pressure. if both the compressor and turbine are 75% efficient, compute the net power output in Btu/hr. account for variable specific heat.
a photomicrograph was taken at a magnification of 500x and it was determined that the average number of grains per
Cooling/Dehumidification of an air stream, A 1000 m3/minute air stream at atmospheric pressure is at a temperature of 82.2oC and a humidity of 60%. We want to cool the air + water vapor to 8.9oC to condense the water vapor.
the velocity of a lift increases uniformly from zero to its maximum value at mid-height (1.4m) in 7.5s and then decreases uniformly to zero in 7.5s. The peak power output is 6kW when the velocity is maximum, determine the maximum lift force provid..
