Minor-loss pressure drop
Inputs
User-entered aggregate coefficient for the stated fittings/local effects; no coefficient is selected or inferred.
User-entered density at the stated condition; property lookup is excluded.
User-entered velocity at the coefficient reference section; passage geometry is not derived.

Calculate local pressure and equivalent head loss from an aggregate loss coefficient, density, and reference velocity.
Δpminor = ΣK·ρv²/2; hminor = Δp/(ρg)
When
- User-entered aggregate minor-loss coefficient
- Declared density
- Incompressible local-loss arithmetic
Don’t
- This is a user-entered aggregate-coefficient minor-loss arithmetic screen only. It does not choose or derive fitting coefficients, calculate friction or major loss, size pipe, model networks, elevation, compressibility, cavitation, transient effects, viscosity/temperature variation, pressure rating, equipment selection, safety, or approval.
