Specific Internal Energy

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Specific internal energy, abbreviated as u, is the internal energy per unit mass.

 

Specific internal energy formula

\(\large{ u =  \frac{U}{m}   }\) 
Symbol English Metric
\(\large{ u }\) = specific internal energy \(\large{\frac{Btu}{lbm}}\)  \(\large{\frac{kJ}{kg}}\) 
\(\large{ U }\) = internal energy \(\large{Btu}\) \(\large{ J }\)
\(\large{ m }\) = mass \(\large{ lbm }\) \(\large{ kg }\)
