Sensible heat from field airflow calculator

Use measured airflow and temperature difference to estimate sensible heat at standard air conditions.

Units

q_{\text{air}} = 1.08 \times Q_{\text{air}} \times \Delta T

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

q_{\text{air}} = 1.08 \times 2200 \times 16 = 38{,}016

Symbol	Meaning	Unit
$q_{\text{air}}$	sensible heat rate at standard air conditions	Btu/h
$Q_{\text{air}}$	measured air volume flow	cfm
$\Delta T$	air temperature difference	°F

Symbol	Meaning	Unit
$q_{\text{air}}$	sensible heat rate at standard air conditions	W
$Q_{\text{air}}$	measured air volume flow	L/s
$\Delta T$	air temperature difference	K

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
