Pressure Drop in Pipe Fittings and Valves

WebThe flow impedance matrix P displays the resistance characteristics related to system topology, whereas the dynamic state of the system is represented by a vector H of kinetic energy. The flow impedance matrix P changes weakly with time as the fluid density and possibly the Reynolds number change (at low Reynolds numbers). WebIt is difficult to understand why, but Crane believed that the resistance factors (K) that were determined in this way would be constant for all flow rates for a given size of fitting.
