Hydraulics engineering is the branch where you will get all the details about water and its types of machinery.
Hydraulic Machines are defined as that branch of Engineering, that deals with the Machine run by water under some head or raising to some higher level.
Before starting the study of hydraulic machines you have to know about the properties of water. Hence you will get all details here.

So, Below are The Properties of Water at rest and motion
Properties of Liquid
Density of Water
So, the mass per unit volume at a standard Temperature and Pressure is known as the Density of Liquid.
It is denoted by “rho”.
Specific Weight
So, The Weight per unit Volume, at Standard Temperature and Pressure, is known as the Specific Weight of Liquid. Denoted by “w”
Specific Gravity
It is the ratio of its Specific Weight to that of a Standard Temperature.
Compressibility
The variation in its Volume, with the variation in its Pressure, is known as the Compressibility of Water.
Hence Water is considered to be an incompressible liquid.
Surface Tension
It is the property, which enables it to resist Tensile Stress. It is due to Cohesion between the Molecules at the surface of a liquid.
Drops of rain sphere because the liquid surface has a tendency to reduce its surface as small as possible.
Capillarity of Water
So, The Phenomenon of rising Water in a tube of smaller diameter is called the Capillary rise.
Viscosity
The property of Liquid that controls its rate of flow is known as “Viscosity of Water”.
So, What is the difference between Mass and Weight?
MASS
So, it is the amount of matter contained in a given body and does not vary with the change in its position on the Earth’s surface.
WEIGHT
It is the amount of pull, that the Earth exerts upon a given body; therefore the Weight of the body will vary with its position on the earth’s surface.
Besides this information, you are suggested to read something more from below engineering books
