Air at 1 atm and 25°c with a speed of 5 m/s flows parallel to and on both sides of a flat plate maintained at 75°c. the length of the plate is 1 m. a. find the velocity and thermal boundary layer thickness at the trailing edge. b. find the wall shear stress at the trailing edge. c. find the rate of heat transfer at the trailing edge (9) d. find the rate of heat transfer from the entire plate (q') e. find the average wall shear stress over the entire plate. f. find the drag per unit width over the entire plate.

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

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
