Hi all,
I want to evaluate convection heat loss for a short cylinder but all correlations are said to be valid for long cylinder (Churchill and Chu, etc). Does anybody know to what extent a cylinder can be considered short or long and so typical correlations can provide a goog estimation for it?
Thanks in advance
