The rated … WebFeb 2, 2024 · The flow at 20 psi (called Q 20 or distribution system capacity) is then calculated using this equation. (1) Where Q 20 = flow at 20 psi residual, Q t = flow …
WebA fire hydrant flow test is a process of flowing water out of at least one fire hydrant while obtaining the required pressures (static, residual, and pitot) needed to calculate the amount of water in gallons per minute (GPM) … 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) and residual pressure (at the calculated flow rate) are then plotted on a graph to produce the water supply curve. Please read NFPA-291 for Hydrant Flow Test procedures and …
