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.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
