SUMMARY

The discussion focuses on calculating the pumping requirements for transferring 100 megalitres of water daily from a river to a dam located 100 meters uphill, over a distance of 25 kilometers. Key factors include determining the total head required for the pump and the electrical power necessary for operation. Participants emphasize the importance of knowing the dam's elevation and selecting an appropriate pipe size to account for velocity and head loss calculations.

PREREQUISITES
  • Understanding of hydraulic head calculations
  • Knowledge of pump power requirements
  • Familiarity with pipe sizing and flow velocity principles
  • Basic principles of fluid dynamics
NEXT STEPS
  • Research "Hydraulic head calculation formulas" for accurate assessments
  • Explore "Pump power requirements for fluid transport" to determine energy needs
  • Learn about "Pipe sizing techniques for water transport" to optimize flow
  • Investigate "Head loss calculations in long-distance piping" for efficiency analysis
USEFUL FOR

Engineers, hydrologists, and project managers involved in water resource management and infrastructure development will benefit from this discussion.

How is following calculated ?
Pumping water from river, up a hill 100 metres high, it then runs downhill into a dam.
Need to deliver 100 megalitres a day, the pipe will be concrete lined steel and the distance about 25 km.
What is total head required from the pump and what is the electrical power needed.

Is this homework? You will have to show what you've tried so far, because it's not ethical for us to simply solve the problem for you.

And you need to know what the elevation of the dam is too...
 
Agreed with Mech. btw you're also going to need a pipe size for velocity and subsequent head loss calcs.
