4) We solved the problem of heat conduction with a viscous heat source during the lecture with the following boundary conditions. Repeat this problem and find the temperature profile, but this time assume that at x=b, the boundary condition is no heat flow (qx = 0) Top surface moves with velocity v = R v₁(x) To Stationary surface T(x)

Transport Phenomena Question

Estimate the natural convection heat transfer coefficient of the horizontal pipe. The temperature of the outer surface of the pipe is 120 ° C. The ambient air temperature is 25 ° C. The outer diameter of the pipe is 10 cm. Convection coefficient = Answer W / m² ° C.

Air at 300 K flows across one side of a flat plate at a velocity of 15 m/s. The plate measures 2.0 m in the direction of flow and 1.0 m wide. If the surface temperature is 400 K, find the convective heat transfer. How much of the plate experiences laminar flow?
