Momentum flow rate formula
Web13 mei 2024 · The thrust is then equal to the exit mass flow rate times the exit velocity minus the free stream mass flow rate times the free stream velocity. F = (m dot * V)e - (m dot * V)0 The first term on the right hand side of this equation is usally called the gross thrust of the engine, while the second term is called the ram drag. WebSluice gate flow metering is often used to measure flow rate in open channels. Sluice gates are also often used to modulate flow. The sluice gate flow rate measurement is based on the Bernoulli Equation and can be expressed as:. 1/2 ρ v 1 2 + ρ g h 1 = 1/2 ρ v 2 2 + ρ g h 2 (1). where. h = elevation height (m). ρ = density (kg/m 3). v = flow velocity (m/s)
