WebTo use the chart, locate the air temperature along the left column and the relative humidity along the top. The cell where the two intersect is the heat index. For example, an air temperature of 90° F and a relative humidity of 60% intersect at a heat index of 100°. Web5 Apr 2024 · Draw a straight line from our .85 SHR to the index point on the chart. Plot out from the return air conditions intercept to the enthalpy scale to find the BTU content per pound of air. In this case, the specific enthalpy of this air is 25.6 BTU/pound of dry air. nelly blithe
