SUMMARY

To determine if a pump is adequate for extracting mucky water from a pool, one must consider the pump's specifications provided by the manufacturer, including flow rate and suction lift capabilities. Key equations include Bernoulli's equation, which incorporates principles of energy and momentum conservation, alongside calculations for mass and density conversions. The characteristics of the mucky water, such as the size of debris, significantly influence the pump's performance and the selection of an appropriate nozzle for effective water dispersion.

PREREQUISITES
  • Understanding of Bernoulli's equation and fluid dynamics
  • Familiarity with pump specifications and performance metrics
  • Knowledge of mass and density calculations
  • Experience with nozzle selection for fluid dispersion
NEXT STEPS
  • Research pump specifications for effective suction lift and flow rate
  • Study Bernoulli's equation in detail for practical applications
  • Explore techniques for calculating mass and density in fluid systems
  • Investigate different nozzle types and their impact on water dispersion
USEFUL FOR

This discussion is beneficial for engineers, fluid mechanics students, and anyone involved in water management or pump system design, particularly in scenarios involving contaminated or debris-laden water.

How do I know if a pump I have is strong enough to suck up a pool of mucky water? What equations would I use?

And how do I calculate the pressure with which the water would be discharged?
Then finally how do I determine the correct nozzle to disperse this water?

This is not a homework question but a real world problem!
Thank you :)

If you already have a pump, then you can read the manufacturers notes on the matter.
The manufacturer will give you a bunch of information about the proper operation of the pump.

This is not something you would calculate as much as try it and see.

The basic equations are:
Bournoulli's equation, with conservation of energy and momentum ... and some for converting masses and densities. But what you mean by "mucky water" will be important - what is the largest article size for example? Does the pump have to contend with leaves and bits of stick or stone?

Real life is messy.
