Content WebDec 22, 2024 · The flow rate formula, in general, is Q=Av Q = Av where Q is the flow rate, A is the cross-sectional area at a point in the path of the flow and v is the velocity of the liquid at that point. In some situations, such as that of water flowing in a riverbed, calculating A is difficult, and the best you can do is an approximation. dynasty warriors 8 loading screen freeze

WebFlow rate (gpm) = Velocity (ft/s) x Area (in2) 0.3208 Note: Fluid is pushed or drawn into a pump Pumps do not pump pressure, their purpose is to create flow. (Pressure is a result of resistance to flow). Torque and horsepower relations: T = HP x 63025 ÷ RPM HP = T x RPM ÷ 63025 RPM = HP x 63025 ÷ T T = Torque, inch-lbs RPM = Speed, revs / minute WebMar 2, 2024 · A = the contributing drainage area (acres) to the point of design that produces the maximum peak rate of runoff.
