Pump and piping sizing

head are related. Pressure will be produced due to the weight of water at the bottom of a tank and the same is true of a piping system. The head or in this case static head is the height of water above the location of interest. Figure 3 Pressure in a tube vs. pressure at the bottom of a tank. Table 1 Pressure to head values for water.

Water injection (engine) - Wikipedia

In internal combustion engines, water injection, also known as anti-detonant injection (ADI), can spray water into the incoming air or fuel-air mixture, or directly into the combustion chamber to cool certain parts of the induction system where "hot points" could produce premature ignition. In jet engines it increases engine thrust at low speeds and at takeoff.

Spray Distribution | On-Site Sewage Facilities (OSSF)

Spray distribution systems for onsite wastewater treatment are much like a lawn sprinkler system. They spray treated wastewater over the surface of a yard. Unlike a subsurface dispersal system, a spray distribution system requires the greatest level of wastewater pretreatment because of the risk of human contact. This in turn increases the cost of the advanced pretreatment system, because it ...
