hi friends
The attached file is MATLAB code for solar irradiation on tilted surface. Why for latitude=60 and surface angle=60, total irradiation at the night (e. g. 1 or 2), is positive but it should be negative (n=356).
Hello dear friends Can we assume thermally fully developed flow for a flow in a duct with constant wall temperature? It is assumed there is transient energy equation that means temperature varies...
