It is the term used in the case of pipe flowing under pressure, it is the circumference of the circular section, while in the case of a rectangular open channel flow, it is the sum of the base and the two sides.

The weight of the body of fluid defined as the earth’s gravitational pull of the body is given by the equation:
It is the term to denote the temperature range between the highest and lowest temperature recorded for a particular day.
A mechanical device which when installed in the pipe will extract energy from the system.
A dimensionless number or parameter in dynamic similarity expressed as the ratio of the inertia force to pressure forces is known as:
The stability of a floating body is determined by the relative position of the center of gravity of the floating body and its metacenter. At tilted position when the metacenter M is below the center of gravity, the two forces, buoyant force and the weight of the body, is said to be in the state of:
Water that flows from the atmosphere to the earth’s surface in any variety of forms is known as:
In pipe flow, applying the Bernoulli equation from one section (upstream side) to another section (downstream side) the total energy on one section (downstream side) is expressed as:
A system of streamline and orthogonal lines which show the idealized flow pattern for a given system of boundaries.
In an open channel flow, the discharge at a certain section can be measured by the use of the weir, given by the equation:
$Q = \frac{2}{3}C \sqrt{2g} ~ LH^{3/2} + \frac{8}{15}C \sqrt{2g} ~ \tan (\frac{1}{2}\theta) ~ H^{5/2}$
where Q is the discharge, C is the coefficient of discharge, H is the head, g is gravitational acceleration. This formula is for:
