6 A suitable pump is selected by entering the two values manometric head H mano = 8.332 meters and the discharge capacity Q = 5 l/s in the performance diagram of the pumps. 7 The pump nearest the intersection point is the right pump for this particular appliion. If two pumps are ideally at the intersection point, both pumps can be used.
expected flow rate that you would obtain for different pipe sizes assuming the pipe or tube is kept at the same level as the connection to the main water pressure supply and has a 100 feet of length (see Figure 4a). Table 1 Expected flow rates for 100 feet of pipe of various diameters based on available pressure.

Outlet Inlet Low-Pressure Fluid High-Pressure Fluid Fluid Carried Between Teeth and Case pFigure 2. A gear pump is a type of positive-displacement pump in which
Pipe Water Velocity and Minimum Pipe Diameter. Used to calculate the velocity of water in a pipe. Bigger pipe is more expensive, but keeping the water velocity low is important to limit pressure losses due to friction, water hammer, and pipe movement due to …
Fuel Pump & Pipe Sizing Calculator. This pump and pipe sizing tool is applicable for diesel generator and boiler fuel systems. It is based on the use of positive displacement pumps that are sensitive to suction line conditions, so the first couple of screens ask for information regarding the layout of the main tank(s) relative to the loion of the pumps.
Step 6) Select the type and size of effluent delivery pipe. Note: Choose a friction loss to ensure a flow velocity between 61-150cm (2-5ft) per second. The pipe size selected will affect the amount of friction loss the pump must overcome to deliver effluent. Step 7) Calculate the equivalent length of pipe for pressure loss due to fittings: P7

Plastic Epoxy coated steel Cement asbestos Galvanized steel New steel Aluminum with couplers 15 year old steel. Maximum Allowable Pressure Loss: psi kPa feet of water bar m of water.
velocity of flow in the suction pipe of centrifugal pumps should be kept between 2 and 3 ft/s in order to prevent cavitation. Table 5 lists the maximum flow rates recommended for different ID (internal diameter) pipe sizes using the 5 ft/s rule. Many friction loss tables give both the friction loss and velocity for any given gpm and pipe size.
a bigger pump, often it is easier to change the pipe or tube than to change the pump. In practice, to get the optimal system you have to select the pump capacity (i.e. flow rate) and head in conjunction with the right pipe or tube size to get the flow rate you intend at the destination.
range of pressures and discharge rates that the pump produces. 1. Measure the head-discharge curve in the following steps: 2. Connect the head-discharge apparatus to the pump discharge with sufficient lengths of straight pipe to obtain an accurate flow rate measurement. Figure 1. Pitot tube flow rate meter. Figure 2. Pump capacity measuring apparatus, including a pressure
With mechanical pumps, the pump cycles as the receiver fills and empties. The instantaneous flowrate while the pump is discharging can often be up to six times the filling rate and it is this instantaneous discharge flowrate, which must be used to calculate the size of the discharge pipe. Always refer to the pump manufacturer for data on sizing
With pipe diameter calculator pipe internal diameter is calculated using the simple relation between flow rate, velocity and cross-section area (Q=v·A). To calculate internal pipe diameter, you should only enter flow rate and velocity in corresponding fields in the calculator and click calculate button to get results.

Keywords:Submersible pump, Total Dynamic Head(TDH), Friction losses, Dynamic water level, pumping level, vertical rise, pipe length, fittings equivalent in feet or meter Introduction In Nigeria, the rate at which bore hole drilling is extensively adopted is high both
Feb 28, 2017· That is fast - but then 36 mm is a big pipe, and the flow velocity of 16 m/s is not unreasonable. Pointing the outlet of this pipe up in the air, such a jet of water could reach about 12 m high - considerably less than the 40 m head of water needed to generate the 4 bar of excess pressure. This makes sense as an order of magnitude.
Nov 17, 2014· The first (typically largest) is the elevation difference. Here, you simply measure the vertical distance (in feet) from the top of the pump in the pump chaer to the discharge point — the elevation of the discharge laterals. The second component is the friction loss in the supply pipe and laterals.
Jan 01, 2018· Six steps to pump sizing. In order to size a pump, engineers need to estimate the temperature, density, viscosity and vapor pressure of the fluid being pumped. Pump sizing can be accomplished in six steps, as follows: Find the total dynamic head, which is a function of the four key components of a pumping system, such as the one shown in Figure 1
Volume Discharge. The following table may be used to estimate the volume discharge from a level pipe. Full Pipe – Measure horizontal distance ‘X’ for water to fall 305mm. Consult table for approximate flow. Partial Flow – Proceed as above to get approximate flow. Measure height ‘Y’ of water in pipe. Calculate 300 ‘Y/D’ to get
Nov 23, 2016· Capacity of each pump is 100 m3/h. So, to meet LNG requirement at pump A we have to operate two pumps simultaneously. In this system, I have assumption of length and pipe diameter of each pipe section. Please see the picture. First of all, to determine required discharge pressure of pump, you need to consider pressure loss.
Static losses are due to differences in either elevation or pressure between the inlet and the discharge. In some booster pump systems, the discharge could be in a pressurized holding tank. So tank pressure must be taken into consideration during design. In a typical JES lift station, the force main discharges to gravity in either a manhole or
Apr 13, 2015· The ideal pipe size for this condition is 5.535 inches, but this example is limited to given pipe sizes. Table 4 shows that a 5-inch pipe has an inside diameter of 5.047 inches and a 6-inch pipe has an inside diameter of 6.065 inches. Process Fluid. The fluid properties also affect the head loss in a pipeline.
Jul 20, 2012· In this test a submersible pump is lowered at a suitable depth and the pump is run for a fixed time (say 1 hr.) in steps. In each step the pump is made to lift water at very low, low, medium and high discharge rates using a Glove Valve in the delivery pipe to maintain a constant discharge for the particular step.

1 Answer1. Active Oldest Votes. 1. Centrifugal pumps typically go by nominal pipe size for the inlet and outlet connections. The first nuer is typically the inlet, and the second is the outlet. Normally the outlet is smaller (which is why you''ll see 10"x8" centrifugal pumps but never 8"x10"). This is partly due to mechanical efficiency and
Apr 26, 2010· In sewage pumps, the discharge size should also be selected so the minimum velocity is 2 feet per second or more. This is referred to as the scouring velocity to avoid clogged pipes. The liquid in the discharge pipe must be turned a minimum of once every pump cycle. This means the run time, at the selected gallons per minute (GPM) flow rate
pipe size 1.5" - 13GPM pipe size 2" - 21GPM System Load Sizing (as a general rule) Sump systems: Caculate basement square footage, divide by 100 and then multiplied by 2.50 will equate the GPM (i.e 500 sq.ft basement will equate to 12.5 GPM)
In terms of diameter, discharge pipe diameter should normally match the discharge flange on the pump but can be larger to reduce friction losses and decrease system pressure. On the suction side, the diameter can be the same size, but oftentimes engineers select a size or two bigger, thus requiring an eccentric reducer.
Feb 26, 2012· Pump Discharge Nozzle Size Vs. Pipe Size - posted in Industrial Professionals: I am sizing a pump for a new process conditions and try to use the same model with some of the existing pump to have synergy in terms of spare pumps. The pump suction pipe is 4 inches with discharge pipe 3 inches. The pump is sized with suction flange of 3 inches and discharge …
How to size a pump: What is required/desired flow? 5 GPM Determine TDH First, let’s calculate friction loss! Friction loss = total length X friction loss (straight pipe) factor + friction loss (fittings) Friction loss = ( 922 ’ X 1.8 ’/ 100 ’) + ( 3 ’ X 2 ) (1.8’/100’) Friction loss = 16.60 ’ + .108 ’
The final cost of medium transfer through the piping is largely defined by the size of pipes (diameter and length). Specially developed formulas, specific for certain types of operation, are used to calculate these values. A pipe is a hollow cylinder made of metal, wood or other material used to transport fluid, gaseous and granular media.
