This specific work calculator finds the work done per unit mass, a common quantity in thermodynamics and turbomachinery. Enter the total work and the mass above.
Formula
Specific work w = Work ÷ Mass
Example
5,000 J over 2 kg: w = 5,000 ÷ 2 = 2,500 J/kg.

Frequently Asked Questions
How do I calculate specific work?
Divide the total work done by the mass involved. The result is in joules per kilogram.
Where is specific work used?
In thermodynamics and gas turbines, to compare work output independent of the mass flow.
What units does specific work use?
Joules per kilogram (J/kg) in SI units.
