Flow Velocity Area to Flow Rate Calculator
The volumetric flow rate formula used by this calculator is: Q = v · A. Symbols. Q = Volume flow rate; v = Flow velocity; A = Crosssectional area; This formula assumes uniform flow conditions within the entire crosssectional area, without any friction losses near to surfaces. Flow Velocity Measured. Enter the speed at which the substance is moving.

Use Bernoulli's Equation to Calculate Pressure Difference ...
Because Bernoulli's equation relates pressure, fluid speed, and height, you can use this important physics equation to find the difference in fluid pressure between two points. All you need to know is the fluid's speed and height at those two points. Bernoulli's equation relates a moving fluid's pressure, density, speed, and height from Point 1 .

Isentropic Flow Equations NASA
Apr 05, 2018· Isentropic flows occur when the change in flow variables is small and gradual, such as the ideal flow through the nozzle shown above. The generation of sound waves is an isentropic process. A supersonic flow that is turned while the flow area increases is also isentropic.

Pressure and buoyancy Boston University Physics
The relationship between pressure and depth is often exploited in instruments that measure pressure. Two pressure gauges based on this principle are the closedtube manometer and the opentube manometer, which measure pressure by comparing the pressure at one end of the tube with a known pressure at the other end.

Part IV: How differential pressure ... Flow Control Network
Other flowmeters do not measure volume, velocity or mass but rather infer the flow through the flowmeter from other measurements. Differential pressure flowmeters are commonly used to infer the flow rate in a pipe by measuring the differential pressure produced across a restriction. Differential pressure flowmeters such as orifice plate, Venturi, nozzle, variable area, and target flowmeters .

May 28, 2016· The higher the velocity of a fluid (liquid or gas), the lower the pressure it exerts. This is called Bernoulli's Principle. Fluid pressure is caused by the random motion of the fluid molecules. When the fluid speeds up, some of the energy from that random motion is used to move faster in the fluid's direction of motion.

What is the difference between pressure and head?
May 31, 2016· The pump selection of a pump is driven by the following main parameters: – Head (H) – Flow rate (Q) – Fluid characteristics (ρ, γ, T ..) Sometimes head can be confused with pressure during pump choice. As a matter of fact there is a strict relation between them which is defined by the fluid specific gravity, so the relation is fluid dependent.
