An ideal reheat rankine cycle with water as the work- ing fluid operates the boiler at 15,000 kpa, the reheater at 2000 kpa, and the condenser at 100 kpa. the temperature is 450°c at the entrance of the high-pressure and low-pressure turbines. the mass flow rate through the cycle is 1.74 kg/s. determine the power used by pumps, the power produced by the cycle, the rate of heat transfer in the reheater, and the ther- mal efficiency of this system.

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

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
