Air at 35C, and 4m/s is flowing parallel a building wall 40

Air at 35C, and 4m/s is flowing parallel a building wall 40 m long and 8 m high. Wall temperature is maintained at 25C. Assume air properties; Pr = 0.7; v=2.5.0X105, p=1.25 kg/m, k=0.030W/m.K. Explain or justify your solution by stating the assumption; a. Calculate Nu at the end of wall. b. Give correlation to calculate Nu for entire wall c. Give correlation for Nu at a location one meter from leading edge of wall. d. Calculate the heat transfer coefficient for the first 1m of wall. e. Calculate Nu for the last 5 m of the wall section.
