We use a cooling fan static pressure is how it

　　When using a cooling fan, often see the word HIP property, which is what the concept of it, following the Shanghai Tang Electronic Technology Co., Ltd. trillion for everyone to use the fan static pressure is how is it?

　　A 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, static table

　　3, the 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 when you spit mention the amount of air pressure and temperature must remember this place, so that the intake air quantity. Fan

　　4, the standard state air:

　　Temperature of 20 ° C, atmospheric pressure 760mmHg, moist air humidity of 65% for standard air, at this time the weight per unit volume of air (known as ratio by weight) was L2Kg / m * 35, the reference state air:

　　Temperature O ° C, atmospheric pressure 760mmHg, moist air humidity of 0% for the standard air, at this time the weight per unit volume of air (known as ratio by weight) was 1.293Kg / m * 3. In Nm * 3 / min, said.
