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 9L/min and
discharge pressure 0.2MPa.
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 9L/min of the fluid, with the following
calculation;
9L/min ÷ 0.45 = 20L/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 1000 mPa

can be used.
