So a hydraulic jump downstream is good evidence that critical flow has occurred. Note that it is not important to know exactly where critical flow occurs. It is enough just to know that it has occurred for the formula to work. In the laboratory, the depth of flow above the weir can be measured so that critical depth flow can be determined.
The fluid used in hydraulic machines is almost always an oil of some sort. And what’s amazing is the force is almost always multiplied in the process. You give a little push in the beginning and get an even bigger result. The following picture shows the simplest possible hydraulic system, a simple hydraulic.
Whenever an external pressure is applied on any part of a fluid contained in a vessel, it is transmitted undiminished and equally in all directions.
In general, the hydraulic head, or total head, is a measure of the potential of fluid at the measurement point. It can be used to determine a hydraulic gradient between two or more points. In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that.
This equation relates the ratios of force to area in any hydraulic system, provided that the pistons are at the same vertical height and that friction in the system is negligible. Hydraulic systems can increase or decrease the force applied to them. To make the force larger, the pressure is applied to a larger area.

16 a typical hydraulic system with two fluid-filled cylinders, capped with pistons and connected by a tube called a hydraulic line. A downward force [latex] \overset\to f_1 [/latex] on the left piston creates a change in pressure that is transmitted undiminished to all parts of the enclosed fluid.
Given these simple formulas, try to answer the questions below. Exercises: a hydraulic press has an input cylinder 1 inch in diameter and an output cylinder 6 inches in diameter. Assuming 100% efficiency, find the force exerted by the output piston when a force of 10 pounds is applied to the input piston.
The resistance coefficients are in most cases found through practical tests and through vendor specification documents. If the resistance coefficient is known, than we can calculate the pressure drop for the element.
The slope of the hydraulic grade line is hl/l and is often called the hydraulic gradient. The symbol i is often used to represent the hydraulic gradient. The hydraulic conductivity, k, is a constant for a given porous medium.
