Acentrifugal air (γ = 1.4) compressor raises the stagnation pressure from 93.3kpa at impeller inlet to 400kpa at diffuser outlet. the stagnation temperature at the compressor inlet is 293k. if the isentropic efficiency of the compressor is 0.8, calculate the stagnation temperature (in k) at the outlet of the diffuser. your answer must be rounded correctly to one decimal place. do not include the unit (k) in your answer.

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
