Hose Flow Capacities Pressure Drop Pressure drop in psi (pounds per square inch) per 10 feet of hose (smooth bore) without fittings. Fluid specifiion: Specific gravity = 0.85; Viscosity = v = 20 centistokes (C.S.), (20 C.S. = 97 S.S.U.) Pressure drop values listed are typical of many petroleum based hydraulic oils at approximately +100ºF
Flow, expressed in gallons per minute (GPM), determines the speed at which a hydraulic cylinder extends or a hydraulic motor turns. Flow is produced by the pump. Pressure, expressed in pounds per square inch (PSI), determines the amount of force exerted. Pressure occurs when flow meets resistance. Pressure is not produced, but is tolerated by

In any fan system, the resistance to air flow (pressure) increases when the flow of air is increased. As mentioned before, it varies as the square of the flow. The pressure required by a system over a range of flows can be determined and a "system performance curve" can be developed (shown as SC) (see Figure 5.7). This system curve can then be plotted on the fan …

Friction loss is pressure used to overcome resistance while forcing water through fire hose, pipes, and appliances. To calculate the friction loss, it is necessary to know the following: • the volume or quantity of water flowing (expressed in gpm) • the size of the hose • the length of the lay Friction loss is independent of pressure when the gpm remains constant in the same size …
The frictional resistance to which fluid is subjected as it flows along a pipe results in a continuous loss of energy or total head of the fluid. Fig 1 illustrates this in a simple case; the difference in levels between piezometers A and B represents the total head loss h in the length of pipe l. In hydraulic engineering it is customary to refer to the rate of loss of total head along the pipe
3-1 Pressure and flow are the key ingredients to a hydraulic system. Pressure, along with the size of the cylinders dictates the force the system has available to use. This was explained in the third principal. The amount of fluid the pump can move dictates how fast a cylinder will move. This is measured in GPM or gallons per minute. It should be noted at this time that all a hydraulic …
In all these cases, when the flow is turbulent, we use the same friction factor correlations that are used for circular pipes, substituting an equivalent diameter for the pipe diameter. The equivalent diameter . D e, which is set equal to four times the “Hydraulic Radius,” R. h. is defined as follows. Cross-Sectional Area 4 4. e h. Wetted Perimeter. D R = = ×. In this definition, the term
Figure 2: Flow near rough and smooth walls may be laminar or turbulent (or an unsteady mix of both) depending on the specific circumstances involved. Note that even for smooth pipes the friction factor is not zero. That is, there is a head loss in any pipe, no matter how smooth the surface is made. This is a result of the no-slip boundary

The effects on the predicted flow rate are then given in three graphs, where in turn two of the variables are kept constant and the flow rate is plotted against a range of values of the third.
