Discussion Overview

The discussion revolves around a hydraulic problem involving a 24-inch diameter water main operating at 40 lbs/sq. in. Participants are tasked with determining the height to which water will shoot from a small hole drilled in the top of the water main. The conversation is exploratory in nature, focusing on the assumptions and equations that can be applied to solve the problem.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that reasonable assumptions need to be made to approach the problem.
  • Others emphasize the importance of showing work and detailing the equations and factors used in the calculations.
  • A participant hints that the problem may be simpler than it appears, suggesting it might not require a complex equation.
  • There is a discussion about whether the problem is primarily hydraulic or ballistic in nature, with some arguing that both aspects could be relevant.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the approach to the problem, with multiple competing views on the nature of the problem and the methods to solve it remaining unresolved.

Contextual Notes

Participants have not specified the assumptions they are making, and there is uncertainty regarding the definitions of hydraulic and ballistic aspects in this context.

This is not a homework problem, just a discussion problem between engineers,. I would like to see what anwers others get.

Given: A 24 inch diameter water main is operating at 40 lbs/sq. in.. A small hole is drilled in the top of the water main (not buried).

Find: To what height will the water shoot?


That's all the given info you get, make reasonable assumptions as needed.

Doesn't matter if it's homework or now, you need to show your own work first. What equations and factors did you use? What answer did you get?

Hint: it's a surprisingly easy question.

On the surface it seems like a very easy question, it might not be a three term equation.

Is it a hydraulic problem or a ballistic problem. I think both are involved.
