Calculating TDH

[krugan]

When it comes to valves and calculating the TDH for a pump, are there two different pressure drops you need to find?

The pressure drop caused by friction (K factor) and the pressure drop caused by flow separation (Cv factor)?

Use one or the other. K if your units are SSI, Cv if units are English, as in gpm/psi^0.5.
