You have a constant area frictionless combustion chamber. at the entrance to the combustion chamber the mach number is 0.2 and the stagnation temperature is 675 k. the mach number is 0.47 at the exit to the combustion chamber. = 1.4 and cp = 1 kj/kgk. a) what is the stagnation temperature at the exit of the combustion chamber? b) what is the ratio of the exit stagnation pressure to the entrance stagnation pressure? c) how high can the stagnation temperature rise in the combustion chamber before the flow reaches m = 1?

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
