Discussion in 'Extreme and Water Cooling' started by Swimming_Bird, Mar 14, 2004. Swimming_Bird Member. Joined: Jul 10, 2003 Messages: 485 Location: Washington, DC. What would be the result of running two pumps (both if they are the same pump model and if they arnt) running in parallel or serial? My guess would be. Flow through pipes in parallel. When pipes of same lengths and different diameters are connected separately in order to increase the discharge, such arrangement or connection of pipes will be considered as pipes in parallel. Let us define the concept of pipes connected in parallel. If a main pipe is divided into two or more than two branches.

For many pump application problems, cavitation is the most commonly encountered. It occurs with all types of pumps, rotary, centrifugal or reciprocating, caused by insufficient system inlet pressure to the pump. This can be due to an inlet system restriction, excessive fluid viscosity or excessive pump speed Pumps running in parallel will increase flow (Q), but not head (H). Pumps are operated in parallel when two or more pumps are connected to a common discharge line and share the same suction conditions. Water pressure boosting applications use, for example, pumps from the CR range to ensure steady flow through a common discharge line Parallel vs. Series Piping Definitions Parallel-Equally manifolding the inlet water pipe and outlet water pipe in multiple heater installations. Having equal number of fittings; as well as, lengths of pipe. Series- Piping the outlet of one heater into the inlet of the next. Why shouldn't I pipe in series? Piping in series can cause the first.

What are the advantages and disadvantages of series and parallel pumps? Wiki User. ∙ 2013-03-11 00:56:29. Add an answer. Want this question answered? Be notified when an answer is posted Inline booster pumping station -two pumps in parallel This layouts is used when one pump is able to deliver the required head but not able to deliver the required flow. In this case we use two or more pumps in parallel. If more than three pumps are needed or when the pumps get large, we should go to an offline booster pumping station Series/parallel pump operating in series (or pressure) mode In the parallel mode, water from the source enters the eyes of both impellers together at the same pressure, and is discharged from both impellers together, into a common delivery. Water inlet First impeller Outlet Second impeller Low pressur parallel is to increase the flow rate meanwhile when pump in series is to pump the fluid, in this case water, to a specific height that we want. Hypothetically, if two pumps are combined in parallel, the flow rate will be twice as much as if a pump were to be in series for a given head

System Availability is calculated by modeling the system as an interconnection of parts in series and parallel. The following rules are used to decide if components should be placed in series or parallel: If failure of a part leads to the combination becoming inoperable, the two parts are considered to be operating in series. What Is a Parallel Circuit? Much more common than series circuits are those wired in parallel—including most household branch circuits powering light fixtures, outlets, and appliances. A parallel circuit is also a closed circuit where the current divides into two or more paths before coming back together to complete the full circuit

In a positive-displacement (PD) pump, a discrete amount of fluid is trapped, forced through the pump, and discharged. A gear pump is an example of a PD pump (Figure 2). This pumping principle produces a pulsating flow, rather than a smooth flow. Its output flow tends to vary little with respect to the pressure at the pump outlet, because the movin Richard W. Hanks, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 VI.B.2.a Positive displacement pumps. Positive displacement pumps include gear pumps, piston pumps, plunger pumps, and progressing cavity pumps. All PD pumps have in common the fact that they are volumetric devices in which a fixed volume of fluid is drawn into the pump, pressurized, and discharged at.

Pump characteristics—such as flow, pressure, efficiency and brake horsepower—are shown graphically on a pump curve. The first item to look at is the size of the pump. The size of the pump, 2x3-8 is shown in the upper section of the graph. The numbers 2x3-8 indicates: The outlet (discharge port) is 2 inches In the previous series resistor network we saw that the total resistance, R T of the circuit was equal to the sum of all the individual resistors added together. For resistors in parallel the equivalent circuit resistance R T is calculated differently.. Here, the reciprocal ( 1/R ) value of the individual resistances are all added together instead of the resistances themselves with the inverse. 23.
