Specific heat formula

\(\large{ c = \frac{ Q  }{m  \; \Delta T }  }\)
Symbol English Metric
\(\large{ c }\) = specific heat \(\large{\frac{Btu}{lbm-F}}\) \(\large{\frac{kJ}{kg-K}}\)
\(\large{ m }\) = 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 \(\large{F}\) \(\large{K}\)

 

Related formula (Eckert number)

Symbol
\(\large{ c }\) = specific heat
\(\large{ U }\) = characteristic flow velocity
\(\large{ Ec }\) = Eckert number
\(\large{ \Delta T }\) = temperature change
