Need to work out the Pressure Drop of fluids moving through a tube or pipe? Use our Pressure Drop Calculator. If the set of conditions entered in the model generate negative answers, then clearly it is necessary to adjust the variables as appropriate until a realistic result is obtained. With this being the case, they will be accurate to within 10% of the actual results obtained. The graphs above are generated from calculations assuming the hose to be in good condition and laid in a straight line. If the head is given in metres of water, each 1-metre head (3.28 ft) induces 0.1 bar (1.47 psi.) pressure.Īll formulae for finding the amount of fluid that will flow through a hose at a given time, are approximate. The pressure is sometimes stated as ‘head of water’. The surface character of the bore, the number, and shape of bends incorporated in the run of the hose also influence the flow rate. The quantity of fluid that will be discharged through a hose depends on the pressure applied at the feed end, the hose length and bore diameter.
