   Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring to the diagram on the right, a pressure tank is generally pressurized when empty with a "charging pressure" P c, which is usually about 2 psi ...

4. Draft (water) - Wikipedia

   en.wikipedia.org/wiki/Draft_(water)

   It is also possible to use a gravity siphon to draft water for a small lift, and this technique is often used in forest fire suppression, where portable reservoirs of 1,000 to 3,000 US gallons (5 to 10 m 3) are filled with water and small hoses are used downhill of the tanks. The nozzle pressure is proportional to its distance below the ...

5. Hard suction hose - Wikipedia

   en.wikipedia.org/wiki/Hard_suction_hose

   Flexible suction hose, also known as a suction hose, is a specific type of rigid fire hose used in drafting operations. When using this technique, the fire engine draws water for fire fighting from an unpressurized supply, such as a portable water tank, pool, or other static water source, instead of drawing water from a pressurized water supply, such as a fire hydrant.

6. Portable water tank - Wikipedia

   en.wikipedia.org/wiki/Portable_water_tank

   A portable water tank is a temporary collapsible tank designed for the reserve storage of water in firefighting, emergency relief, and military applications. These tanks can be either supported or unsupported. The supported tanks have a steel or aluminum frame and range in size from 600 to 5,000 US gallons (500 to 4,160 imp gal; 2,300 to 18,900 ...
