Question 1 20 Marks) Solve equation = 0 For the temperature distribution in a plane wall if the internal heat generation per unit volume according to D?T+*= 0 9 = 4, + The boundary conditions that apply are: x = 0, T = To and T = Tu at x =L Question 2 [30 Marks) Local atmospheric pressure in Tshwane, Gauteng (elevation 1714 m), 95.85 kPa. Air flows at mean velocity 7.98 m/s over a plate whose dimensions are 1.65 m by 6.84 m flat plate whose temperature is 138 C. The temperature for air at 95.85 kPa is given to be 20 C. Determine rate of heat transfer from the plate if air flows parallel to the; a) 1.65 m side and b) 6.84 m long side
