Specific Heat

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Specific heat, abbreviated as c, is the amount of energy required to increase one gram of a substance by 1 degree celsius.

 

Specific heat formula

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

\(\large{ c = \frac{ U^2 }{ 2 \; Ec \; \Delta T }   }\)

Symbol English Metric
\(\large{ c }\) = specific heat \(\large{\frac{Btu}{lbm-F}}\) \(\large{\frac{kJ}{kg-K}}\)
\(\large{ U }\) = characteristic flow velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ Ec }\) = Eckert number \(\large{dimensionless}\)
\(\large{ m }\) = mass \(\large{lbm}\) \(\large{kg}\)
\(\large{  Q }\) = specific heat capacity \(\large{\frac{Btu}{lbm-F}}\) \(\large{\frac{kJ}{kg-K}}\)
\(\large{ \Delta T }\) = temperature change \(\large{F}\) \(\large{K}\)
