Calculation method

Calculation method

Total loss coefficient

dp=sum K rho V²/2.

Total fitting pressure loss (Pa)

dp=sum K rho V²/2.

Fitting head loss (m)

dp=sum K rho V²/2.

Individual fitting pressure losses (Pa)

dp=sum K rho V²/2.

Symbols and units
a
Fitting loss coefficients K
b
Flow velocity (m/s)
c

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Calculation uses the entered values and stated mathematical model; quantities must use the labelled units. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. dp=sum K rho V²/2.
