Calculate the amount of contamination (Lbs or Kg) that passes through hydraulic components and bearings annually by selecting a unit of measurement, flow rate, hours/days, the current, and target ISO codes. Calculate the flow rate by entering the inside pipe diameter and the velocity to receive gallons per minute or other periods or units of measurement. To use the viscosity calculator, select the temperature and then the ISO code to calculate centistokes. You can enter an element to look up nearly any Hy-Pro element upgrade or replacement with the interchange or cross-reference tool.
