Generally laminar flow will continue on a smooth flat plate until a critical reynolds number is reached. however, the flow can be tripped by adding roughness or a wire to the leading edge of the plate, causing the flow to be turbulent. consider expressions for the local heat transfer coefficients for laminar and turbulent conditions: hlam(x)= (1.74w/m^1.5. k)x^-0.5hturb(x)= (3.98w/m^1.8.k)x^-0.2find the average heat transfer coefficients, in w/m^2.k, for laminar and turbulent conditions for the following cases. case a: plate is la = 1.2 m in length. case b: plate is lb = 0.6 m in length.
