# Sensible Heat

Sensible heat, abbreviated as Q, is the heat added to a substance which increases its temperature but not the phase is called sensible heat. The sensible heat added to a substance can be readily calculated. The quantity of heat in a body or the amount of heat energy which a body gains or loses in passing through a temperature range is measured in thermal units.

## Sensible Heat Formulas

\(\large{ Q = m\;c \; \Delta T }\) | |

\(\large{ Q = 1.1 \; cfm \; \Delta T }\) | (HVAC) btu/hr |

### Where:

\(\large{ Q }\) = sensible heat

\(\large{ cfm }\) = cubic feet per minute

\(\large{ m }\) = mass

\(\large{ \Delta T }\) = temperature differential

\(\large{ c }\) = specific heat
