1732 – Henri Pitot discovers how to measure the pressure from the speed of a fluid using a Pitot tube. [13] 1738 – Daniel Bernoulli publishes Hydrodynamica discussing the mathematical relation between pressure and velocity of fluids according to Bernoulli's principle. [1] 1742 – Anders Celsius designs a thermometer with the Celsius scale.
A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. [ 1 ] Examples of equipment that might use hydraulic fluids are excavators and backhoes , hydraulic brakes , power steering systems, automatic transmissions , garbage trucks ...
Hydraulics is a branch of science and mechanical engineering concerned with the use of fluids to perform mechanical tasks. Subcategories This category has the following 10 subcategories, out of 10 total.
The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history.

Hydraulics and other studies [1] An open channel, with a uniform depth. Open-channel hydraulics deals with uniform and non-uniform streams. Illustration of hydraulic and hydrostatic, from the "Table of Hydraulics and Hydrostatics", from Cyclopædia, or an Universal Dictionary of Arts and Sciences, edited by Ephraim Chambers, 1728, Vol. 1
In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor f D, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.
In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid.TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.
