SUMMARY

The discussion centers on calculating the water pump requirements for a 1.5-meter diameter granite sphere fountain, which will operate on a 3mm water sheet. The user, Snadeep, is tasked with providing these calculations for a client’s mall project. Key considerations include the mechanical engineering aspects of lifting heavy objects and ensuring safety against potential failures. Suggestions include using a hemispherical cup to support the sphere and conceal the mechanics, as well as referencing a physics paper for further understanding.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Knowledge of mechanical engineering design for water features
  • Familiarity with pump specifications and calculations
  • Experience with safety considerations in heavy object handling
NEXT STEPS
  • Research fluid dynamics calculations for water fountains
  • Learn about pump selection criteria and specifications
  • Study mechanical design principles for supporting heavy objects
  • Explore safety measures for water features involving heavy materials
USEFUL FOR

Design engineers, mechanical engineers, and professionals involved in the construction and design of water features, particularly those working with large, heavy installations like granite sphere fountains.

Dear All,

I want to calculate water pump required for lifting the 1.5m dia. Granite ball on 3mm water sheet.
kindly help ma as the earliest.
Thanks

Thanks for your reply, but this I'am already having but not getting how to calculate. kindly post something in easy method if you have thanks

What is the application? Why are you trying to do this? Is this for a schoolwork assignment?
 
No Sir, It's not school assignment, I'm having one client he want this type of water fountain in his upcoming mall project. I've to provide him calculations for this granite Sphere water fountain.

What is your background? If you don't have the mechanical engineering background for this assignment, it may be best for you to hire a local professional engineer to design the system. Asking for this kind of design advice on the Internet is not very professional, especially when it involves such heavy objects...
 
Sir,
I'm a estimation and design engineer and working for water fountain company from last four year, but this is my first time I'm facing such kind of water feature that's why I'm looking for some basic information so that i can work on it and Sir, I'm a mechanical engineer. Thanks

Especially spherical ones...

When the power fails, the ball will crash down. Calculating how to design to resist damage from that might be even harder. Also design for pranks where kids will try to push the rock to the side. A fake ball made of foam might be a solution.

Another solution could be a hemispherical cup on a supporting pillar. The cup could have small holes for water under pressure. If it lifted the back only one mn, the ball would still move and spin slowly. But if anything goes wrong, the cup catches the ball. A surrounding water column would conceal the cup and the pillar, thus creating this illusion that it is holding the ball up.
