The Borda-Carnot Equation calculator computes the mechanical energy loss of a fluid due to sudden expansion.
INSTRUCTIONS: Choose the preferred units and enter the following:
Mechanical Energy Loss: The calculator returns the mechanical energy loss as a change in pressure in units of Pascals (Pa). However, this can be automatically converted to other pressure units via the pull-down menu.
The Borda-Carnot equation in fluid dynamics is an empirical description of the mechanical energy losses of the fluid due to a (sudden) flow expansion. It describes how the total head reduces due to the losses. This in contrast with Bernoulli's principle for dissipationless flow (without irreversible losses), where the total head is a constant along a streamline. Theis used for open channel flow as well as in pipe flows:
ΔE = ε•½•ρ•(v1-v2)2
