Bernoulli's Principle(?) Problem

AI Thread Summary
The discussion revolves around a physics homework problem involving fluid dynamics, specifically applying Bernoulli's Principle. The main tasks are to calculate the speed of water exiting a faucet and the gauge pressure in a main pipe. The user successfully determined the water speed to be 2.7 m/s using flow rate calculations. However, they express confusion regarding how to apply Bernoulli's equation to find the gauge pressure based on the height of the water column. The user seeks further assistance to adapt the equation for their needs.

Homework Statement


The water supply of a building is fed through a main entrance pipe 6.0 cm in diameter. A 2.0 cm diameter faucet tap positioned 2.0 m above the main pipe fills a 25 liter container in 30 s.
(a) What is the speed at which the water leaves the faucet.
(b) What is the gauge pressure in the main pipe.
Assume that the faucet is the only outlet in the system.

Homework Equations


Flow rate = A/v (cross-section area / velocity)
Possibly(?) Bernoulli's Equation
Possibly(?) v = \sqrt{2gh}

The Attempt at a Solution


Since the flow rate would be 50 *10^{3} m^{-3} / 60 S, I used that, which I know, and divided it by the area \pi0.01^{2}, and I got the right answer of 2.7 m/s.

After that I'm lost as for what to do.
Help please!

Edit: Upon further analysis, I think that I need to convert this to the pressure based on the height of the column, but how would I adapt Bernoulli's equation to fit my needs?

I didn't want to do this, but...

BUMP!
 
I really need this problem, so here goes the underhanded tactic again.

Bump...
(not that I needed to say that, but, whatever)
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
