If the head loss and pressure drop is given then we find volumetric flow rate or mass flow rate. 2. Now if mass flow rate and pressure drop is given, in this case we easily can determine head loss. 3. And at the last case mass flow rate and head loss given, then pressure drop also can be determine.
