Frequently Asked Questions

Common questions about Sensible Heat from CFM, formulas, and typical use cases.

What formula is used for sensible heat from airflow?

A common HVAC relationship is sensible BTU/h = 1.08 × CFM × ΔT.

What does ΔT represent in this calculation?

ΔT is the dry-bulb temperature change across the coil or air path in degrees Fahrenheit.

Can this estimate required CFM from load?

Yes. Rearranging gives CFM = BTU/h ÷ (1.08 × ΔT).

Does this include latent load?

No. This calculation covers sensible load only and does not include humidity (latent) effects.
