Air enters a convergence-divergence nozzle with 1.5 mpa pressure, 700 k temperature and very low velocity. there is a normal shock wave stands at the exit of the nozzle with mach 2.6. 3.a determine the pressure, temperature and density before and after the nsw 3.b quantify the entropy change across the nsw. 3.c determine the velocities before and after the nsw

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
