  2. Fire hose - Wikipedia

    en.wikipedia.org/wiki/Fire_hose

    The usual working pressure of a firehose can vary between 8 and 20 bar (800 and 2,000 kPa; 116 and 290 psi) while per the NFPA 1961 Fire Hose Standard, its bursting pressure is in excess of 110 bar. (11,000kPa; 1600psi) [2] Hose is one of the basic, essential pieces of fire-fighting equipment. It is necessary to convey water either from an open ...

  3. Centimetre or millimetre of water - Wikipedia

    en.wikipedia.org/wiki/Centimetre_or_millimetre...

    A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...

  4. Water flow test - Wikipedia

    en.wikipedia.org/wiki/Water_flow_test

    From this test hydrant, a static pressure and a residual pressure will be measured. The other hydrant, known as the flow hydrant, is usually the nearest hydrant away from the test hydrant. The flow hydrant is fitted with a diffuser device containing a pitot tube that measures stagnation pressure in the middle of the stream while the hydrant is ...

  5. Fire-resistance rating - Wikipedia

    en.wikipedia.org/wiki/Fire-resistance_rating

    The completed test sample is inserted into a furnace such that one side is exposed to a fire. The test is terminated when the fire stops successfully meet the test criteria in minimizing the amount of heat and smoke allowed to pass through the assembly, when the fire penetrates the fire stops. This determines the fire stop F-Rating.
