Total sensible heat transfer rate
Webresult, the direction of the total heat transfer rate, which is a sum of sensible heat transfer and latent heat transfers. The concept of enthal py potential [4] is very useful in quantifying the total heat transfer in these processes and its direction. The sensible (Q S) and latent (Q L) heat transfer rates are given by: Q S = h o A S (ti ta) WebApr 25, 2024 · Step #1 – Plot the given conditions on the Psychrometric Chart. Step #2 – Get the h1 and h2 values from the Psychrometric Chart 34.9 and 23.2. Step #3 – Enter all values into equation. q = CFM x 4.5 x ∆h. q = 2,000 x 4.5 x 11.7 = 105,300 Btu/hour. With this information we can solve for how many btu’s are being supplied to the air.
