I have a 3.5 Mtr dia, 10 mtr height milk tank, How do I convert the pressure reading to quantity of milk at bottom temperature which varies approx 10 deg C to 4 deg C, please suggest how to calculate the level and volume of milk?
First you will need to determine the density of the Milk at different temperatures, if you do not know this, then you can use this guide to the physical properties of milk.
To improve the accuracy of your readings you can also use local gravity instead of standard gravity (9.80665 m/s2). If you do not know your local gravity then use this tool which calculates local gravity from latitude.
Once you know the density (SG) and the local gravity you can use this tool to convert the pressure reading into liquid level.
To determine the volume of milk in the tank use this vertical cylindrical tank contents calculator.
Example Calculation
- Specific Gravity → So in your example the SG of milk at 10°C would be 1.033.
- Gravity → If the location was New Delhi which has a latitude of 28.613333 and an elevation of 216 metres, the gravity would be 9.79151 ms-2.
- Level → A 500 mbar pressure reading would represent a milk level of 4.9433 metres.
- Volume → A 4.9433 metre level of milk would represent a volume of 47560 litres.
