downstream pressure
1Pressure drop — For other uses, see Pressure Drop (disambiguation). Pressure drop is a term used to describe the decrease in pressure from one point in a pipe or tube to another point downstream. Pressure drop is the result of frictional forces on the fluid as… …
2Pressure vacuum breaker — A Pressure Vacuum Breaker (PVB) is a type of backflow prevention device,used to keep non potable (or contaminated) water from entering the water supply. A PVB is similar to an atmospheric vacuum breaker (AVB), except that the PVB contains a… …
3Pressure regulator — A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allow high pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various… …
4Cerebral perfusion pressure — Cerebral perfusion pressure, or CPP, is the net pressure gradient causing blood flow to the brain (brain perfusion). It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having… …
5Reduced pressure zone device — A Reduced Pressure Zone Device (RPZD, RPZ or RPZ valve) is a type of backflow prevention device used to protect water supplies from contamination. An RPZD is considered suitable for high hazard applications, that is, where the consequence of… …
6Choked flow — is a compressible flow effect. The parameter that becomes choked or limited is the velocity or the mass flow rate. Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and… …
7Orifice plate — Flat plate, sharp edge orifice ISO 5167 Orifice Plate An orifice plate is a device used for measuring the volumetric flow rate. It …
8Valve — This article is about the flow control device. For the game developer, see Valve Corporation. For the electronic component, see Vacuum tube. For other uses, see Valve (disambiguation). These water valves are operated by handles. A valve is a… …
9Check valve — Tilting disc inconel check valve …
10Accidental release source terms — are the mathematical equations that quantify the flow rate at which accidental releases of air pollutants into the ambient environment can occur at industrial facilities such as petroleum refineries, petrochemical plants, natural gas processing… …
