Log mean temperature difference, ft applied to heat exchangers. problem 4.9-2, p351. oil flowing at the rate of 5.04 kg/s (cpm = 2.09 kj/kg. k) is cooled in a 1-2 heat exchanger from 366.5 k to 344.3 k by 2.02 kg/s of water entering at 283.2 k. the overall heat transfer coefficient u0, is 340 w/m^2 .k. calculate the area required. (hint: a heat balance must first be made to determine the outlet water temperature.)

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
