Question

Hi. please show the step-by-step solution how qw can be get. I try to do it but i've stuck. the final answer is at the last line. This is from viscous fluid flow, frank white, 3rd edition. At the 2nd last line, please explain how term AFTER (Tw-Te) can be found?

4.2 Repeat the integral flat-plate heat-transfer analysis of Sect. 4-1.7 by using the parabolic velocity from Eq. (4-11) and the quartic temperature profile 2y 2y 8r This is a realistic temperature profile, satisfying the five boundary conditions T(O) Tw a2Tay2(0) = 0, T(8) = Te, aray(6) = 0, and a2Tay2(6) = 0. Substitution into the integral energy equation, Eq. (4-21), gives )] , where ζ=-< 1 15 42'
