Material Calculator - Cross Section, Flow Rate and Quantity

Calculator for the cross section area, the velocity of the flow and the volume in a certain time. This can be e.g. at a river or anything else which is flowing. Cross section and velocity are taken at the same place. Please enter three values and select the units you want. The fourth value will be calculated.

Example: a hose with a cross section area of 2 cm² fills a basin with 100 liters in three minutes. Then the flow rate is 2.78 meters per second.
