A0.2-m-long and 25-mm-thick vertical plate (k = 15 w/m-k) separates the hot water from the cold wa- ter. the plate surface exposed to the hot water has a tempera- ture of 100°c, and the temperature of the cold water is 7°c. determine the temperature of the plate surface exposed to the cold water (ts). hint: the t. has to be found iteratively. start the iteration process with an initial guess of 53.5°c for the ts, c

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
