Temperature vs Viscosity Table
Figure 28: Temperature vs Viscosity Table
You can populate the entire viscosity table, all 100 index points, with the Viscosity
Calculator tool You need to know two liquid viscosities and the corresponding
liquid temperature and enter them in the yellow cells
OTEE:
N
Please pay close attention to appropriate units when entering data into
the fields above The temperature units are in Fahrenheit (° F), the Density
units are in Pounds per Gallon (Pounds/Gal) and Viscosity is in
Centi-Stokes (cStk) The temperature engineering unit (T1 and T2)
is degrees Fahrenheit (° F) and kinematic viscosity (V1 and V2) is in
centistokes (cStk)
To populate the table:
1 Type a liquid name in the white field near the top of the table
2 Click the bullet next to the
ASTM
or
Andrade
method for computation of
viscosity The ASTM equation is typically more accurate
3 Input the lesser temperature value and the corresponding viscosity value in
the top-most yellow data fields of the viscosity calculator (T1 and V1), and the
greater temperature value and the corresponding viscosity value in the middle
row of yellow data fields of the viscosity calculator (T2 and V2)
OTEE:
N
Do not place the lesser temperature on the middle row of yellow cells
because that causes the viscosity calculator to fail and possibly corrupt
profile data
4 Specify minimum and maximum temperature values This tells the viscosity
calculator over which range in temperature to populate the temperature vs
viscosity table
OTEE:
N
Exceed your intended operating temperature by 5…10 degrees or more
so that temperature range is not exceeded and proper viscosity correction
takes place in the flow processor
5 Click the
Fill
button to populate the temperature vs viscosity table
