AI Thread Summary
Designing a water supply system for fire safety in a neighborhood involves determining flow and pressure requirements at the most distant point in the system. Establishing a pressure maintenance system, such as a dam, water tower, or pump, is crucial to meet these requirements while accounting for pressure drops in the mains. Water capacity must be calculated based on the source, whether it be a well or dam. If the system serves both fire and domestic needs, simultaneous usage must be considered. Proper planning ensures adequate water supply for fire safety in residential areas.

I'm not a civil engineer, but I think the process is something like this.

You need to determine your flow and pressure requirements at the most remote location on your system. Once you know that, you need to create a pressure maintenance system, such as a dam, a water tower/tank/pump, or a well and pump, to deliver that flow and pressure plus allowable pressure drop through the water mains. You also need to determine how much water capacity you will need from your source be it well, or dam, or other. If it is to be a combined fire and domestic water system you will need to account for both potentials occurring in part simultaneously.

Example flow and pressure may be 50 psi flowing 1200 gpm at the most remote location.

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
