Volume Conversion Factors Imperial Gallons x 1.2 = US Gallons Liters x 0.2642 = US Gallons Cubic meters x 264.2 = US Gallons Barrels (US) Liquid x 31.5 = US Gallons Barrels (Oil) x 42 = US Gallons Imperial Gallons x 4.55 = Liters Cubic Feet x 28.32 = Liters Cubic Inches x 0.016 = Liters Viscosity Conversion Factors Centistokes = Centipoise ÷ Specific Gravity SSU* = Centistokes x 4.55 Degree Engler* x 7.45 = Centistokes

TDH: Tổng áp động lực áp suất cần được tạo ra trong bơm, khi bơm theo tốc độ mong muốn. Total dynamic head Total Dynamic Head (TDH) is the total height that a fluid is to be pumped, taking into account friction losses in the pipe. TDH = Static Lift + Static Height + Friction Loss where: Static Lift is the height the water will rise before arriving at the pump (also known as the 'suction head'). Static Height is the maximum height reached by the pipe after the pump (also known as the 'discharge head'). Friction Loss is the head equivalent to the energy losses due to viscose drag of fluid flowing in the pipe (both on the suction and discharge sides of the pump). It is calculated via a formula or a chart, taking into account the pipe diameter and roughness and the fluid flow rate, density and viscosity. Calculate your Total Dynamic Head (TDH) in three easy steps ==>> xin vào đây To choose the right pumping system you need to first calculate your
