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, "220V AC Cooling Fan" 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 "220V AC Cooling Fan" spit out the amount of air time, we must remember the pressure and temperature of the place, so that the intake air quantity.
