4. During a cold winter day, wind blows parallel to a 4 m high and 10 m long wall of a house. If the air outside is at 5°C and the surface temperature of the wall is 15°C, The general non-dimensional correlation for flow over a flat plate is: Nu =(0.037 Re, 08-871)Pr¹/3 where the fluid properties are evaluated at the bulk temperature. If the wind blows at 55 km/h, determine: i. the Reynolds number ii. the convection heat transfer coefficient, and iii. the rate of heat transfer from the wall.
