A plane wall with constant properties is initially at a uniform temperature T0. Suddenly, the surface at x = L is exposed to a convection process with a fluid at T infinity (> T0) having a convection coefficient h. Also, suddenly the wall experiences a uniform internal volumetric heating q that is sufficiently large to induce a maximum steady-state temperature within the wall, which exceeds that of the fluid. The boundary at x = 0 remains at To.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

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

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
