220V AC Cooling Fan of static pressure

1, "220V AC Cooling Fan" hydrostatic unit
    N: Newton, 1n = 0.101097Kgf
    Pa: Pascal, Pa = N / m ^ 2
    mmAq: Aq = Aqua (water) referred to
    mmAq known as mmH2O; 1mmAq = 1Kg / m ^ 2
    atm: atmospheric pressure; atmospheric pressure equal to the pressure at a 0 ℃ dry state of 760mmHg.
    Because mercury is 13.5947 times the weight of the water, so they equal 10332mmH2O one atmosphere pressure bar: 1 bar = 0.00001Pa = 10-5Pa
2, "ios版雷竞技官网入口 " amount of air
Blower suction air flow per unit time is called the amount of air (Air volume, Air quantity), typically Q (m * 3 / min) for the amount of the gas when the amount of intake air Laid-called air-cooling fan occasions also called air volume. (Capacity) gas according to their pressure, temperature and volume changes, so the reference to "ios版雷竞技官网入口 " spit out the amount of air time, we must remember the pressure and temperature of the place, so that the intake air quantity.
