Helium at a free stream temperature of T = 25°C is in parallel flow over a flat plate of length L = 3 m and temperature T, = 85°C.
However, obstacles placed in the flow intensify mixing with increasing distance x from the leading edge, and the spatial variation of
temperatures measured in the boundary layer is correlated by an expression of the form T(°C) = 25+ 60 exp (-550xy) where x
and y are in meters. Determine the local convection coefficient, in W/m².K, at x = L. Evaluate the average convection coefficient , in
W/m².K, for the plate.
