Posted By: an02ewfilm coeficients
Posted By: RobLInside they use 7.7W/(m^2.degC)
Outside 25W/(m^2.degC)
Posted By: djhWhat is a film coefficient in your context? Some quick googling makes it seem like something imported into THERM
Posted By: WillInAberdeenThe thickness of the supposed boundary layer depends on the speed of air flow (so the wind speed, and natural convection speeds, which depend on the height and orientation and temperature) and the surface roughness, plus the physical properties of the air which depend on weather etc. The idealised thickness for heat loss calcs may be different for friction calcs.
