Sensible Heat

Written by Jerry Ratzlaff on . Posted in Thermodynamics

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
