Laminar flow normally persists on a smooth flat plate until the critical Reynolds number value is reached. However, the flow can be brought to a turbulent state by adding a roughness to the front edge of the plate. For a particular situation, experimental results show that the local heat transfer coefficients for laminar and turbulent conditions are: Hlam (x) = 1,74.x^-0,5 Hturb (x)= 3,98.x^-0,2 Calculate the average heat transfer coefficients for laminar and turbulent conditions for plates of length L = 0.1 m and 1.0 m.
