Consider an air compressor used in gas turbine engine. The compressor is being tested in laboratory facility. Air enters the compressor at the ambientpressure (1 bar) and temperature at a density of 1.2 kg/m3, with an average velocity of 1m/sthroughthe inlet area of 0.8m2. Air leaves the compressor at a pressure of 6 bar(absolute),with a density of 3.6kg/m3, through an exit area of 0.2m2. Calculate:a)the averageair velocity at the exit, and b)the magnitude and direction of the force required to keep the compressor fixed in its position.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
