Watts ACV 115

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. 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 pressure is sometimes stated as ‘head of water’. If the head is given in metres of water, each 1-metre head (3.28 ft) induces 0.1 bar (1.47 psi.) pressure.

To begin calculating, enter your figures in the boxes below. If a value is not available for any one of the variables, then please leave the field blank and the program will select its own value.

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.

All formulae for finding the amount of fluid that will flow through a hose at a given time, are approximate. The graphs above are generated from calculations assuming the hose to be in good condition and laid in a straight line. With this being the case, they will be accurate to within 10% of the actual results obtained.

With this tool, it is possible to easily calculate the average volumetric flow rate of fluids by changing each of the three variables: length, pressure and bore diameter. The effects on the predicted flow rate are then given in three graphs, where in turn two of the variables are kept constant and the flow rate is plotted against a range of values of the third.
