Laminar flow normally persists on a smooth flat plate until a critical Reynolds number value is reached. However, the flow can be tripped to a turbulent state by adding roughness to the leading 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) = Alamæª htur (x) - Aturæb Alam = 1.98 a = -0.5 Atur = 4.15 b = -0.3 Calculate the average heat transfer coefficients for laminar and turbulent conditions for plates of length L = 0.2 m and 2.5 m.
