Flow capacity tables
Flow capacity information in this brochure is based on water at approx +20°C with tolerances of +/- 5% in flow volume. If liquids with other specific gravities are used, the equivalent flow capacities can be calculated by using the relevant factors from the table below. |

| Volumetric flow rate (V)
For a given liquid, nozzle flow rate depends on jet pressure (liquid pressure at the nozzle). Flow rates can be altered by varying pressure levels and can be calculated as follows:
