2) Viscosity characteristic
With reference to viscosity characteristic graph (shown below), discharge amount of transported
fluid with higher viscosity can be calculated.
Recommended typical condition B:
Calculate discharge amount of fluid with viscosity 100mPa
･
s in case of discharge rate 4.5L/min
and discharge pressure 0.1MPa.
1. Find ratio of discharge rate to fresh water for the fluid with viscosity 100mPa
･
s from the
graph. Then, it is found to be 45%.
2. After that, convert it to discharge rate of fresh water.
Since discharge rate 45% of fresh water is equal to 4.5L/min of the fluid, with the following
calculation;
4.5L/min
÷
0.45
＝
10L/min
It is found discharge rate 10L/min is necessary for fresh water.
3. Then, refer to flow characteristic graph and calculated air pilot pressure.

Caution
- The viscosity of fluid is affected by operating conditions(temperature, transporting distance etc.)
and fluctuation of ambient temperature.
- Viscosities up to 1000mPa
