Instructions for the section "Online conversion of units of measurement".
1. How to convert pressure units:
Enter a numerical value in the upper box and select the units of measurement in the drop-down menu opposite the upper and lower boxes. The desired pressure value will automatically appear in the lower box.
2. Flow rate, kinematic viscosity, dynamic viscosity are calculated in the same way.
3. To convert kinematic viscosity to dynamic viscosity, you need to fill in two boxes and click on the "Calculate" button.
4. To calculate head and pressure values, fill any 3 boxes and click on the "Calculate" button.
5. To calculate fluid flow velocity in the pipeline, enter the values in two boxes.
6. To calculate net positive suction head, fill in any 5 boxes and click on the "Calculate" button.
7. To calculate losses, fill in all the proposed boxes and click on the "Calculate" button.
