4.62 A steady-state, finite-difference analysis has been performed on a cylindrical fin with a diameter of 12 mm and a thermal conductivity of 15W/m K. The convection process is characterized by a fluid temperature of 25°C and a heat transfer coefficient of 25W/m2 K. If the temperature of the first three nodes, separated by a spatial increment of delta x = 10 mm, are T0 =100 degree C, T1 =93.4 degree C, and T2 = 89.5 degree C, determine the fin heat transfer rate. Determine the temperature at the node 3, T3.

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

On a average work day more than work place firs are reorted

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
