But there are other things that can cause flow, such as a height difference or even a temperature difference. <>>> Current Fuel Pressure . The pressure of a fluid is defined as the force acting per unit area within the fluid. In SI units, pressure is measured by Pascal (Pa) or Newtons per square meter (Nm-2) and, in the imperial system, it is measured by pounds per square inch. endobj endobj If the gas has a larger volume, the weight also affects the static pressure (ex: atmospheric pressure). A fluid will try to flow from high pressure to low pressure. This calculator works with pressure values in either psi or kpa and flow values in either cc/min or lbs/hr. When considering the static pressure of gases and liquids, their sources are different. Flow vs Pressure Calculator.

Pressure is not a vector quantity. This continuous movement of the fluid is known as flow. What causes a liquid or gas (a fluid) to flow? The change in static pressure across the expansion due to the change in velocity is: (P1 − P2) = ρ 144(v2 2 − v2 1 2g) = 62.4lb ft3 144in2 ft2 ((4.09 ft / sec)2 − (9.27 ft / sec)2 2(32.2ft / sec2)) = − 0.466 psi Use this helpful calculator to quickly convert any flow rate or pressure units.

Technically, flow refers to the amount of fluid passing through a given surface. the rate of volume flowing and the rate of mass flowing. If the container is small, the gas pressure can be considered same at every point. The pressure present within fluid can originate from two different factors. endobj Even though it refers to a unit area, it can be referred to the value of a point which is varying from point to point. FREEPHONE 0808 239 6313. This amount of flow can be measured using two parameters; i.e. <> 3 0 obj These two properties are characteristics of the state of fluid. Mostly, the term “flow” refers to the volumetric flow rate.

<> Use this helpful calculator to quickly convert any flow rate or pressure units. Filed Under: Physics Tagged With: flow, Fluid Flow, Fluid Pressure, pressure. In gasses, it is the rate of collision of gas molecules within the container. Here to help.
