Heat and Mass Transfer Sensible heat factor is given by (where S.H. = Sensible heat, and L.H. = Latent heat) (L.H - S.H)/S.H (S.H + L.H) /S.H S.H/(L.H - S.H) S.H/(S.H + L.H) (L.H - S.H)/S.H (S.H + L.H) /S.H S.H/(L.H - S.H) S.H/(S.H + L.H) ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer Two long parallel surfaces each of emissivity 0.7 are maintained at different temperatures and accordingly have radiation heat exchange between them. It is desired to reduce 75% of the radiant heat transfer by inserting thin parallel shields of emissivity 1 on both sides. The number of shields should be Four Three One Two Four Three One Two ANSWER DOWNLOAD EXAMIANS APP
