In the furnace example with return 67°F and supply 113°F, what is the temperature rise (ΔT)?

The temperature rise is how much the air temperature increases from the return to the supply. With a return of 67°F and a supply of 113°F, the rise is 113 − 67 = 46°F. This shows how much the furnace heats the air in this cycle. The other numbers don’t fit the given temperatures because they would require different supply or return values.
