hey, thank you for the response, I found after a long period of searching that if the velocity between 2 to 20 m/s we can calculate the hconv from this hcov= 10.45 - v + 10√v and from this question I found when I can use the equation above that will help in other questions , always simple...

Homework Statement Determine the heat loss per square meter of skin surface due to convection at -40degreeC in moderate wind (0.5 m/s, Kc=10 Kcal/m2-hr-degreeC), assuming that the skin temperature is 26degreeC. Homework Equations hcov= 10.45 - v + 10√v ΔQ/Δt = A hconv (Tskin - Tair) The...
