The Residual pressure and the Static pressure during a flow test should be taken from a fire hydrant that is located as close as possible to the location requiring . If you are designing a fire sprinkler system, use this test (residual hydrant. + separate downstream flow hydrant). Hydrant Capacity Test determines the flow-rate.
