PARTIAL VOLUME app can be used to calculate flow into or out of a vessel during a time period - a draw-down test or level raise test. The vessel can be horizontal or vertical.
All measures are in mm. The horizontal vessel has tripozoidal ISO-heads, which is the most common type in commercial vessels used in Europe.
The raise test is commonly used to measure condensate flows in a paper and board machines. The Dryer Calculaton page calulates condensate loads for the dryers from the raise test result.
The version 2 is completely reprogrammed version of the app (API level 34). Later versions will support Imperial units and vessels according to ASME, which gives marginal difference in volume.
