Question No. 3: During a cold winter day, wind at 55 km/h is blowing 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 is12°C, determine the rate of heat loss from that wall by convection. What would your answer be if the wind velocity was doubled
An insulated wall has a total thermal resistance of 2.5 K/W for an area of 1 m^2. In winter, the room temperature is held at 25 C, and the outside temperature is at -5 C. The convective coefficient for the inside air is estimated as h=10 W/m^2*K, and the convective coefficient for the outside air is estimated as h0=20 W/m^2*K. Calculate the heat loos in watts per 1 m^2 of the wall
When the convection heat transfer coefficient is very large (h → ∞), the convection resistance becomes zero and Ts ≈ T. This situation is approached in practice at surfaces where ------------------------ occur.
An average person generates heat at a rate of 84 W while resting. Assuming one-quarter of this heat is lost from the head and disregarding radiation, determine the average surface temperature of the head when it is not covered and is subjected to winds at 10°C and 25 km/h. The head can be approximated as a 30-cm-diameter sphere. Assume a surface temperature of 15°C for evaluation of ms. Is this a good assumption?
