Calculating Water Speed in a 3-Story Building: Fluid Dynamics Homework Help

AI Thread Summary
To estimate the speed of water from a washbasin in a 3-story building, one must consider the pressure required to reach the second floor, which is 6 meters above ground level. The discussion highlights the importance of pressure head and continuity in fluid dynamics, indicating that without sufficient pressure, water flow will be limited. A conceptual approach likens the situation to a container of water, where creating an opening at the ground floor allows water to flow out, but the overall system must maintain adequate pressure. The challenge lies in determining the necessary conditions for water to effectively reach the upper levels. Understanding these principles is crucial for solving the homework problem.

Homework Statement



There is a building with 3 floors: ground floor, first floor and second floor. Ground floor is at level zero, first floor is 3 meters above it and second floor is 6 meters above the ground level.

The hydraulic system is made in a way that water barely reaches the second floor.

Now I let water run from a washbasin situated on the ground floor: estimate the speed of the water.

Homework Equations


The Attempt at a Solution



I have too many ideas (which is like having none), so I would prefer someone directing me on the right way :)

Thanks :)

me too, but i'll hazard a guess. in order for the water to reach the second floor their must be sufficient pressure in the system to force your basn water out the sink. But i think it depends on contuinity as well. In other words without access to the pressure head of incoming water, it all comes to a standstill, at least at ground level.
 
I was thinking of considering the whole thing like a big container of water, with the top of it open and with the water level stuck at the level of the second floor. Then letting the water run from the washbasin at the ground floor could be like making a hole on the container... it's the more reasonable idea I've come up to, nothing better...
 
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...
