Chapter 7, Problem 7.14P

Consider water at 27°C in parallel flow over an isothermal, 1-m-long flat plate with a velocity of 2 m/s.

1. Plot the variation of the local heat transfer coefficient, $h_x\left(x\right),$ with distance along the plate for flow conditions corresponding to transition Reynolds numbers of (i) $5\times {10}^5,$ (ii) $3\times {10}^5,$ and (iii) 0 (the flow is fully turbulent).
2. Plot the variation of the average heat transfer coefficient ${\bar{h}}_x\left(x\right)$ with distance for the three flow conditions of part (a).
3. What are the average heat transfer coefficients for the entire plate ${\bar{h}}_L$ for the three flow conditions of part (a)?
