Air enters the diffuser of a turbojet engine at 18 kpa, 216 k, with a volumetric flow rate of 230 m3/s and a velocity of 265 m/s. the compressor pressure ratio is 15, and its isentropic efficiency is 91%. air enters the turbine at 1360 k and the same pressure as at the exit of the compressor. the turbine isentropic efficiency is 93%, and the nozzle isentropic efficiency is 97%. the pressure at the nozzle exit is 18 kpa. on the basis of an air-standard analysis, calculate the thrust magnitude, in kn.

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

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
