Static vs residual water pressure
WebDec 27, 2024 · Pitot pressure is used to calculate the flow rate from the hydrant that correlates to the residual pressure being read. The values of Static Pressure (no flow) … Webthe water supply and chosen valve type will allow and still provide the required demand. For Class I hose valves, the static outlet pressure must not exceed 175 psi, and for Class II hose valves, the maximum allowable static outlet pressure is 100 psi. Considering that hose valves are normally manually closed, static outlet pressure is only an
