How to Fix a Water Heater's Leaking Pressure-Relief Valve

Aug 26, 2008 · Leighton asks, "I just drained my hot water heater, and now the pressure relief valve is leaking. Is this something I can replace on my own, or should I call a plumber?"Pressure relief valves sometime develop a drip when opened for the first time in years. If the drip doesn't stop on its own in a day or two, here are the basic steps involved.

Bernoulli's principle - Wikipedia

The low pressure in the throat of a venturi can be explained by Bernoulli's principle; in the narrow throat, the air is moving at its fastest speed and therefore it is at its lowest pressure. An injector on a steam locomotive (or static boiler). The pitot tube and static port on an aircraft are used to determine the airspeed of the aircraft.

HVAC Duct Construction Standards

Because total pressure is less downstream than upstream, a duct construction pressure classification equal to the fan outlet pressure (or to the fan total static pressure rating) cannot economically be imposed on the entire duct system. Pressure in ducts near room air terminals is nearly always below 1/2″ water gage (125 Pa).
