Flows rate (Equivalence) | ||
The most commonly used water flow or airflow unit today is CFM (Cubic Feet per Minute). In countries where the metric system is more common, m3/min or m3/h is sometimes being used, but even there, CFM is the most common unit. | ||

Viscosity is first and foremost a function of material. Sqlpro studio 1 0 144 – powerful database manager. The viscosity of water at 20 °C is 1.0020 millipascal seconds (which is conveniently close to one by coincidence alone). Most ordinary liquids have viscosities on the order of 1 to 1,000 mPa s, while gases have viscosities on the order of 1 to 10 μPa s.

Power (the unit of power of the S.I = Watt) | ||
The power is the unit of energy per unit of time.
C'est cette unité qui est attribuée aux générateurs d'énergie (moteurs, chaudières, etc.) ou à leurs dérivés.
Energie (E en Joules) = W (Puissance en watt) x t (temps en secondes) Par exemple :
Attention ceci ne signifie pas la consommation d'énergie (Il faut intégré tous les rendement et autres pour obtenir la consommation d'énergie équivalente) Il y a 2 unités différentes dans l'utilisation du horse power (HP). La pemière unité (HP = 745,7 watt) utilisée au USA/UK est basée sur l'énergie équivalente pour soulever un poids de 550 livres (pound) au travers 1 pied (foot) en une seconde. La seconde unité (HP = 736 watt) utilisée en Europe continentale est basée sur l'énergie équivalente en énergie à soulever dun poids de 75 kilogrammes sur 1 mètre en 1 seconde. | ||
