Liquid calculator calculates the volume and weight of liquid inside given container at any given height of liquid. The container shapes included such as capsule tank, cylinder tank, vertical capsule tank, vertical cylinder tank, rectangle tank and sphere tank. More than 100+ liquid type for selection such as water, oil, mercury, acid etc. Support for both metric and Imperial system. A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.

成型鏡板+円筒胴による容器の容積、表面積、設定水位における容量を求めることができるアプリです。 容器の板厚と素材の比重を設定して容器の空重量を求めることもできます。また、溶接構造による容器の場合は3点のパーツ(上部鏡板A,胴板L,下部鏡板B)に分けて各部毎に板厚、フランジ長さを個別に設定し重量、容量を精査できます。 さらに、簡易強度計算機能もあり、設計圧力(内圧のみ)と使用材料の許容引張応力(設計温度による)から計算板厚を求めることもできます。 このアプリケーションソフト(PVVS)のご使用は全て利用者の自己責任において行うものとします。 本アプリケーションソフトを運用した結果生じた損害について、作者は一切の責任を負わないものとします。

Verdict
The clearest difference is price: PVVS at Free against Liquid Calculator's $2.99. PVVS also leads on update cadence (every 2 months vs every 28 months). Liquid Calculator's advantage is ads (none vs shown) and iOS requirement (13 vs 15.0). On in-app purchases and device support there is nothing between them.
