Heat is generated uniformly at a rate of 2 × 105 w/m^3 in a wall of thermal conductivity 25 w/m · k and thickness 60 mm. the wall is exposed to convection on both sides, with a fluid temperature of 30°c and h = 50 w/m2 · k on the left side, a fluid temperature of 15°c and h = 12 w/m^2 · k on the right side. (a) determine surface temperature on each side of the wall, and (b) the maximum temperature in the wall.

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

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
