◎ How to determine pressure loss
(1) Seeing the graph of the type of flowmeter to be
used, find the pressure loss coefficient C from the
flowrate (g/min. or kg/h) and viscosity (mPa ・ s).
Dividing this value C by specific gravity d (1 for
water) gives the pressure loss, or
C
ΔP = － － － － (MPa)
d
※1: Pressure loss is calculated with Newtonian fluid.
For Non-Newtonian fluid, please consult OVAL.

(2) For high-viscosity liquids not shown in the graphs, calculate
the pressure loss by the following equation:
μ
2
= C× － － － ×－ － －
ΔP
2 μ

where ΔP : Pressure loss of high-viscosity liquid (MPa)
2
μ : Maximum viscosity shown in the graph (mPa ・ s)
1
μ : Viscosity of high-viscosity liquid (mPa ・ s)
2
d: Specific gravity of high-viscosity liquid (1 for water)
C: Pressure loss coefficient found from the maximum
viscosity curve at a given flowrate
