Repeat Problem 7.11 for the case when the boundary layer is tripped to a turbulent condition at its leading edge.

Data From Problem 7.11

Consider laminar, parallel flow past an isothermal flat plate of length L, providing an average heat transfer coefficient of h_L . If the plate is divided into N smaller plates, each of length L_N = L/N  determine an expression for the ratio of the heat transfer coefficient averaged over the single plate, h_L,N / h_L,₁.
