Bernoulli's theory, expressed by Daniel Bernoulli, it states that as the speed of a moving fluid is raises (liquid or gas), the pressure within the fluid drops. Even though Bernoulli cut the law, it was Leonhard Euler who assumed Bernoulli's equation in its general form in 1752.
Foundry sand testing Wikipedia
Foundry sand testing is a process used to determine if the foundry sand has the correct properties for a certain casting process. The sand is used to make moulds and cores via a a sand casting foundry there are broadly two reasons for rejection of the casting — metal and sand — each of which has a large number of internal variables.
Sand Casting Process, Defects, Design
Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace ...

A mould forming mix of ingredients including sand, a binder, and a catalyst blend is produced. The catalyst blend includes at least two catalysts one of which is slow acting and the other of which is fast acting. The ratio of the fast and slow catalysts used to make up the catalyst blend depends on the time to hardening required, and the temperature of the sand.
