Specific Internal Energy

on . Posted in Thermodynamics

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


Specific Internal Energy formula

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