[TRNSYS-users] About Convective Heat Transfer Coefficient of Wall

[caria.roberto at tiscali.it]

dear users
I have any doubts about Convective Heat Transfer Coefficient of 
Wall: 
1) if I change it does thermal trasmittance change? On the "Wall Type 
Manager" below on value of wall trasmittance there are two standard 
values: those will be change with a new value of Convective Heat 
Transfer Coefficient of Wall?
If I wanted to insert a custom value, does anyone know any formula to 
calculate the coefficient as a function of the difference temperature 
and wind speed? Have I also consider the radiative part?    
thanks in advance
Roberto
