Find the Flow Rate: Water Pipe Down a Hill

AI Thread Summary
To find the flow rate of water through a pipe descending a hill, the height difference is 23 m, with a pipe diameter of 2.7 cm. The water's velocity at the top is 2.41 m/s, and the gauge pressure is 58.3 psi. Calculating the flow rate requires applying principles from fluid dynamics, including Bernoulli's equation. The initial attempts to solve the problem yielded incorrect results, indicating a need for a more thorough analysis or additional factors to consider. Accurate calculations are essential for determining the flow rate in liters per second.

check this, i can't figure it out. A water pipe goes doewn a hill. the level of the pipe at the bottom of the hill is 23 m below the level of the pipe at the top. the diameter of the pipe is 2.7 cm at both ends. water is flowing through the pipe. at the top of the hill, the velocity of the water is 2.41 m/s, and it's gauge pressure is 58.3 psi. find the flow rate of the water through the pipe in L/s. can anyone help?

i tried that already and it doesn't give me the proper results. there's got to be something else.
 

Thread 'Errors and significant figures'

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...
