Air flowing parallel to a 20 m long, 2 m high, 0.20m thick wall with Re= where X is taken from leading edge of wall, Pr -0.7; Wall temperature is maintained at = 4x104*X Ts, while air at T... For each of situation given below give an empirical correlation or equation to calculate Nu, and explain clearly why it is chosen, justification accounts to 50% of grade. a. Heat transfer at the end of wall? [10] b. Heat transfer for the entire wall is required? [10] c. Heat transfer at a location four meter from leading edge of wall? [10] d. Heat transfer for the last 4 meters of the wall? [10] e. Repeat C above if first 2 m are at air temperature while rest of plate at Ts.[10]
