When two centrifugal pumps are connected in series the discharge changes by factor of?

Centrifugal pumps in series are used to overcome larger system head loss than one pump can handle alone.
- for two identical pumps in series the head will be twice the head of a single pump at the same flow rate - as indicated in point 2.
With a constant flowrate the combined head moves from 1 to 2.
Note! In practice the combined head and flow rate moves along the system curve to point 3.
- point 3 is where the system operates with both pumps running
- point 1 is where the system operates with one pump running
Series operation of single stage pumps is seldom encountered - more often multistage centrifugal pumps are used.

What is factor of safety?
Factor of safety is a figure used in structural and geotechnical design applications that provides a design margin over the theoretical design capacity.
What is the shape factor for schedule 80 pipe?
2
What is a un-factored load and a factored load?
Factored loads are inflated loads. Each type of load has a specific safety factor (load factor) added. Un-factored loads are not inflated.
What is the shape factor formula for any shape in image analysis?
nothing, there is no possible answer
What is factor of safety in Crane load lifting?
If SLI is in operating condition then sLI itself will indicates that whether load is in safe mode. But if SLI is not working then one must be considered 40 % factor of safety of crane SWL and in SLI working condition it will be considered 20 % of its SWL.
What happens when lagging Power Factor changes to leading PF?
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
What is slip factor?
a slip factor table is provided to calculate the slip factor in centrifugal ... Another well-known expression for calculating the slip factor
How is the power factor meter connected?
power factor meters are connected across the supply
In an experiment a factor that changes is called a?
A factor that changes in an experiment is called a variable.
How do you calculate gravity factor for centrifugal force?
The gravity force balancing the centrifugal force is mv2/r = mg. The centrifugal force is Del.cP = cmDel.V = mcv/r cos(VR), mv2/r = cmv/r cos(VR) is the Continuity Condition of stable orbit.
When speed is double the centrifugal force also double?
When speed is doubled, the centrifugal (or centripetal) force increases by a factor of 4. One formula you can use (for centripetal acceleration) is: a = v2 / r. Force, of course, is proportional to acceleration.
The factor that changes in an experiment is the variable?
Yes.The answer that changes is the variable
What is the one factor that changes an experiment?
A factor that changes in an experiment is called a dependent variable. It is the variable that is being tested.
A factor that changes during an experiment?
if any factor in an experiment changes, you have a brand new experiment. -A factor in an experiment that can change is known as a variable.
What factor changes in response to a manipulated variable?
The dependant Varible changes.
What is a factor that changes in a experiment?
variable
