Question
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.
