Choked water flow
WebWith these type pumps the excess backpressure (created by choking a pump with a valve) is a free by product of horsepower. As the pump pressure increases, the weight of the water being lifted is reduced and the power required decreases. With centrifugal impellers, restricting the flow rate with a valve reduces the power required proportionally. WebFeb 3, 2016 · As you mentioned in your question, the pressure in the bottle is decreasing with time, which changes the rate of mass flow. What you need to do is solve the choked flow equation over time. It is a non-linear ordinary differential equation, but is fairly easy to solve numerically using the forward-Euler method and a spreadsheet program. The ...

The limiting case of the Venturi effect is when a fluid reaches the state of choked flow, where the fluid velocity approaches the local speed of sound. When a fluid system is in a state of choked flow, a …
WebVenturi flow meters, like all other types of differential pressure flow meters, function on the principles of the Bernoulli equation, which states that as the speed of the flow of a fluid increases, pressure loss occurs. Venturi tubes are available in sizes up to 72” and can pass 25 to 50% more flow than an orifice with the same pressure drop. WebSummary. Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage …
