The specific heat of steel is 0.12 Btu/lb-F, and the convection coefficient is 2 Btu/hr-ft2-F. If the racking enters the oven at room temperature of 70 F and the drying process takes 0.25 hours, calculate the exit temperature of the racking, and the heat and fuel energy loss to the racking with each drying cycle.

Calculating Heat Loss/Gain: To calculate heat loss (or gain), the following formula will be used:, where. Q' is the heat loss in Btus per hour (Btu/H) U is the reciprocal of the R-Value, A is the area of the surface ∆T is the difference in temperature on either side of the wall. You may round the transmission load to the nearest whole number.

(The equation used to calculate heat gain or loss is: q = mc(T. A positive value for q indicates a heat gain while a negative value for q indicates a heat loss. (Acid—base neutralization is an exothermic process, so the water will experience a heat gain and therefore the temperature will rise.)

Sensible heat loss is that loss due to a temperature difference, such as the temperature difference across the building envelope or the temperature difference between the make-up ventilation air and the exhaust air. Latent heat loss is due to evaporation from the pool surface and subsequently exhausting this moisture out of the building or ...
