Atwo-stage air compressor operates at steady state, compressing 10 m^3/min of air from 100 kpa. 300 k, to 1200 kpa. an intercooler between the two stages cools the air to 300 k at a constant 5. pressure of 350 kpa. the compression processes are isentropic. calculate the power required to run the compressor, in kw, and compare the result to the power required for isentropic compression from the same inlet state to the same final pressure. draw the schematic, the p-v, and the t-s diagrams.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

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

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
