5. an insulated, rigid tank is divided into two compartments by a frictionless, thermally conducting piston. one compartment initially contains 1 m3 of saturated water vapor at 4 mpa and the other compartment contains 1 m3 of water vapor at 20 mpa, 800°c. the piston is released and equilibrium is attained, with the piston experiencing no change of state. for the water as the system, determine (a) the final pressure, in mpa. (b) the final temperature, in °c. (c) the amount of entropy produced, in kj/k.

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

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
