question

A non-Newtonian power-law fluid is flowing in a tube which is heatedby steam condensing outside the tube. Calculate the outletbulk fluid temperature for laminar flow, given the followingdata. Rate of flow of fluid = 650lbm/hr Entering temperature of the fluid = 100°F Inside wall temperature = 200°F Density of fluid = \rho = 65lbm/ft^3 Specific heat of fluid = C_p = 0.5 Btu/lbm°F Thermal conductivity of fluid = K = 0.7 Btu/hr°Fft Flow property constants: n' = 0.4 k = 80lbms^n-2 ft^-1 at 117.5°F k = 40lbms^n-2 ft^-1 atT_w= 200°F Internal diameter of tube = 1/12 ft. Length of tube = 7.4 ft.
