Bernoulli - Head Balance
Total-head balance between two points in an incompressible flow - the classical Bernoulli equation for pump/pipe calculations.
Total head 1
20.59m
Total head 2
10.56m
Head loss
10.04m
Formula, assumptions, and limits
Incompressible, steady, no pump/turbine work between points. Applies to ballast lines, fuel lines, cooling-water headers. For pump: add H_P to point 2.
