How do you determine the capacity of a submersible pump?

The submersible pump stage calculation tells you how many stages are required. You find it by dividing the total dynamic head (TDH) by the length of each stage. The TDH is the equal to the sum of the pumping level, head length, drop pipe friction loss and check value friction.

What is the capacity of 1hp submersible pump?

1 HP Single Phase Submersible Pump, Maximum Discharge Flow (LPM): 100 – 500 LPM

Motor Horsepower 1 HP
Head (Water Lifting Capacity) 15 to 50 m
Power Source AC Powered
Maximum Discharge Flow (LPM) 100 – 500 LPM
Discharge Outlet Size (mm) 1 to 2 in

How is pump performance calculated?

Understanding How to Measure a Pump’s Performance

  1. The mass and fluid velocity are related according to the following formula: v=m/pA Head, H.
  2. Maximum efficiency is achieved upon perfect balance between Q and h, particularly at the point between where Q=0 and h=0.

How do you calculate pump speed?

On a scientific calculator Sp = 1/ [(1/S) – (1/ C)], To allow solving easily for the pump’s pumping speed, the speed required to provide 150 liters/sec. at the chamber is 175 liters/sec.

How do you calculate pump size?

Use the pump flowrate calculation: Divide the container volume by the length of time it took to fill up to get the flow rate. 5 gallons / 1 minute = 5 gallons per minute. 5 gallons /30 seconds (0.5 minutes) = 10 gallons per minute.

How do you calculate pump capacity?

Calculations:

  1. Flow Rate (Q) =Q1x1.
  2. Actual Total Head (After Friction Losses) (H) = (h1+h2)+((h1+h2)xf)
  3. Actual Total Head (After Friction Losses) (H)=50+(50×30\%)= 65 Meter.
  4. Pump Hydraulic Power (ph) = (D x Q x H x9.
  5. Pump Hydraulic Power (ph) = (1000 x 0.005 x 65 x9.
  6. Motor/ Pump Shaft Power (ps)= ph / pe = 3 / 80\% = 4KW.

How do you calculate pump LPM?

Flow = (Displacement x RPM)/1000 Flow is in Liter per minute (LPM), Displacement is cc per revolution while RPM is rotation per minute. Q = (90 x 2222)/1000 = 200 l/min (approx).

How many liters per minute does a 1.5 HP pump pumps?

READ:   Is a pipe or cigar better?

My 1.5 HP pump pumps approx 14 L/min and I have purchased 40L/min flow sensors.

How do you calculate pump flow rate?

The formula for determining the flow rate is gallons drawn down (that were measured above), divided by the seconds required for recovery, then multiplied by 60: (Gallons / Seconds) x 60 = Gallons per Minute (GPM) flow rate..

How is pump motor rating calculated?

How do I calculate pump needs?

Decide on the desired flow rate. The needs of your project determine the necessary flow rate of liquid from the pump. Write this value down in gallons per minute (gpm). You won’t be using this value right away, but it will determine which pumps and pipes you consider.

How much power do I need to run a submersible pump?

If there’s no power on site, you need to spec a generator: •Most submersible pumps with 5HP or less are 230V/single phase. You’ll need 1.5kW per motor HP So…a 5HP pump needs a minimum of 7.5kW You also need to spec the right power cable •PVC flat-jacketed wire is the most common.

How do you calculate the power required to run a pump?

Actual power required = (water horsepower) / (pump efficiency). Write efficiency as a decimal (50\% → 0.5). Decide on the desired flow rate. The needs of your project determine the necessary flow rate of liquid from the pump.

How much horsepower do I need for my water pump?

Once you have chosen a pump, check the manufacturer’s info for the pump’s efficiency and write it as a decimal. Divide the water horsepower by this value to find the actual horsepower of the motor you need for your pump. Example: To do 0.18 horsepower of work, a pump with a 50\% (or 0.5) efficiency rating would actually require a 0.36 hp motor.

How do you test a submersible pump?

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.
