A house at the bottom of a hill is fed by a full tank of water 8.0 m deep and connected to the house by a pipe that is 120 long at an angle of 55 degrees from the horizontal to the house. A) Determine the water gauge pressure at the house and B) How high could the water shoot if it came vertically out of a broken pipe in front of the house?

I know that the formulas for pressure are: P= (f/a), P=pgh, and P= (m/v)

Which formulas would I use for parts A and B? Do I need to make any conversions of units?!?!

hmm ,  h = length of pipe * sin (55).

anonymous · Answer

depends on the size of the hole.

anonymous · Answer

approximately the same height as the water tower.

For A you use P=pgh but need to subtract atmospheric pressure because you're asked for gauge pressure.
For B iirc you use a combination of conservation of energy and possibly another fluid mechanics related equation. (Possibly bernouli's equation?)
