During a cold winter day, wind at 55 km/h is blowing parallel to a 4m high and 10m long wall of a house. If the air outside is at 5 degrees Celsius and the surface temperature of the wall is 12 degrees Celsius , determine the rate of heat loss from the wall by convection. What would your answer be if the wind velocity has doubled? From Table A-1: thermal conductivity, k = 0.0246 W/m degrees Celsius viscosity, v = 1.4 x 10^-5 m^2/s Prandtl no. Pr = 0.717

Question
During a cold winter day, wind at 55 km/h is blowing parallel to a 4m high and 10m long wall of a house. If the air outside is at 5 degrees Celsius and the surface temperature of the wall is 12 degrees Celsius , determine the rate of heat loss from the wall by convection. What would your answer be if the wind velocity has doubled?
From Table A-1:
thermal conductivity, k = 0.0246 W/m degrees Celsius
viscosity, v = 1.4 x 10^-5 m^2/s
Prandtl no. Pr = 0.717
