2. Spray nozzle - Wikipedia

   en.wikipedia.org/wiki/Spray_nozzle

   One of the configurations of the solid cone spray nozzle is shown in a schematic diagram. A swirling liquid motion is induced with the vane structure, however; the discharge flow fills the entire outlet orifice. For the same capacity and pressure drop, a full cone nozzle will produce a larger drop size than a hollow cone nozzle.

3. Pressure washing - Wikipedia

   en.wikipedia.org/wiki/Pressure_washing

   A pressure washer is used to remove old paint from a boat. Patio flagstones being pressure washed using a rotary nozzle. Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.

4. Discharge coefficient - Wikipedia

   en.wikipedia.org/wiki/Discharge_coefficient

   In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.

5. Spray (liquid drop) - Wikipedia

   en.wikipedia.org/wiki/Spray_(liquid_drop)

   Nozzle type and capacity: full cone nozzles have the largest drop size, followed by flat spray nozzles. Hollow cone nozzles produce the smallest drop size. Spraying pressure: drop size increases with lower spraying pressure and decreases with higher pressure. Flow rate: flow rate has a direct effect on drop size.

6. K-factor (fire protection) - Wikipedia

   en.wikipedia.org/wiki/K-factor_(fire_protection)

   Using metric units, the volumetric flow rate of a nozzle is given by =, [1] [2] where q is the flow rate in litres per minute ( l/min ), p is the pressure at the nozzle in bar and K is the K-factor is given in units of (/) /.

7. Nozzle - Wikipedia

   Increasing the nozzle pressure ratio further will not increase the throat Mach number above one. Downstream (i.e. external to the nozzle) the flow is free to expand to supersonic velocities; however, Mach 1 can be a very high speed for a hot gas because the speed of sound varies as the square root of absolute temperature.
