Air is compressed in a piston-cylinder assembly from p1=
10lbf/in.2, t1 = 500or to afinal
volume of v2 = 1 ft3 in a processdescribed by
pv1.25 = constant. the mass of air is0.5lb. assuming
ideal gas behavior and neglecting kinetic andpotential energy
effects, determing the work and the heat transfer, each in btu,
using constant specific heats evaluated at500or and
ideal gas properties.

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

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
