Yesterday we published ‘Visco Blender’ on Google Play.
This is another standalone version of the same utility included in Oil Calculator Pro.
The visco blender calculates a blend of maximum ten components, and actually calculates not only the viscosity but also the pour point, flash point and density of the resulting blend.
You can download ‘Visco Blender’ here.
All data entered is stored into a local database and will be saved automatically so that the user can later easily retrieve and edit the information again. There is however only one set of data available, at present it is not possible to save multiple blend configurations under different names.
The visco blender contains two tools: one is the actual blender tool as described above, the other one is a simple fraction calculator, which will be explained further below.
Available controls and fields:
Component number:
This is a drop down list numbered from 1 to 10 and is used to select a specific entry. When you select another entry, any data that has been entered in the current entry is saved; thereafter any existing data for the newly selected entry is loaded into the display.
M³, Mtons and density:
If the user enters a volume and a density, the weight is calculated automatically. Conversely if you enter a weight and a density, the volume is calculated automatically. Units used for these entries depends on whether you have selected SI Metric or Imperial using the options menu: all data is stored in the database in SI Metric form, but is displayed in Imperial units if Imperial units has been set in the settings screen, and values of density and volume are automatically converted accordingly.
Viscosity:
The viscosity is entered in centistokes (cSt) regardless of which unit has been chosen in settings. The resulting blend viscosity is also calculated and displayed in centistokes.
Flash point and pour point:
Flash point and pour point are entered either in °C or °F depending on the unit setting. As with volume and density, the flash point and pour point are stored in the database in °C, and the resulting flash and pour point are calculated in °C, but are displayed according to the unit setting chosen in the settings screen.
Fraction calculator:
The fraction calculator calculates the respective quantities of two components, based on their individual viscosities and the required target viscosity. The user simply has to enter the total quantity, target viscosity and the viscosity of each component, and the app then calculates the required quantity for each component using the Refutas method to reach the target viscosity.
Change settings:
There is an options menu in the top right hand corner of the screen (for newer phones; for older phones the options menu can be accessed using a hardware menu button). When you press this menu, two options show up: the option to switch between SI Metric and Imperial units, and the option to view the ‘About’ screen:
In below screen shot you can see the difference between using Imperial units and SI Metric units:
