  • Pressure 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… …   Wikipedia

  • Pressure 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… …   Wikipedia

  • Pressure 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… …   Wikipedia

  • Cerebral 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… …   Wikipedia

  • Reduced 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… …   Wikipedia

  • Choked 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… …   Wikipedia
