Air enters an insulated turbine operating at steady state at 8 bar, 500k, and 150 m/s. at the exit the conditions are 1 bar, 320 k, and 10 m/s. there is no in elevation. determine the work developed and the exergy destruction, each in kj/kg of air flowing. let to=300k and po=1bar significant change

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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

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
