While that is certainly true, head loss is typically labeled "h" with units of length, and "P" is typically expressed in terms of Pa, psi, etc. There is another typo that I've found just recently: the sudden expansion and contraction equations should be divided by beta^4; beta=dSmall/dLarge.

actually, the "head" has dimensions of length ...

Please use this handbook with extreme caution & doublecheck the equations/formulas. E.g.: there is a vicious typo in equations 1&2. dP is labelled as a _pressure_ drop instead of a head loss. The difference is pressure=pascals=N/m2 head loss = meters Its always a good...
