Question repeat prob but let the surface temperature vary, Ask an Expert

Engineering

Question: Repeat Prob. but let the surface temperature vary sinusoidally from 40°C at the leading and trailing edges to BO°C at the centerline.

Problem: Let air at a constant velocity of 7.6 mis, a temperature of 90°C, and 1 atm pressure flow along a smooth, flat surface. Let the plate be divided into three sections, each 10em in flow length. The first 10ern section is maintained at 40°C, the second at BO°C, and the third at 40°C. Evaluate and plot the heat flux at all points along the 30 cm of plate length, and find the local heat-transfer coefficient.
