    Speed Water
AI Thread Summary
To find the speed of water exiting a shower head, apply the equation of continuity, which states that the mass flow rate remains constant. Gather the pipe's diameter, the number and diameter of the holes, and the water speed in the pipe. Use the formula V = (Xm/s * (pi*(pipe diameter/2)^2))/(number of holes * (pi*(hole diameter/2)^2)) to calculate the speed at the holes. This equation accounts for the change in area as water flows from the pipe to the smaller holes. The resulting calculation will yield an average speed, influenced by factors like pressure and turbulence.

hi,here is my question.

water comes through a shower, the speed in the pipe is Xm/s how does this change when the water comes through the little holes in the shower head. I have the number of holes and their diameter and also the diameter of the pipe.


how would i find the speed of the water when it comes out of the holes of the shower head.

thanks a lot anybody! :) :smile:

Do you know anything about the equation of continuity? If not, look it up in your physics text. It'll help.
 


To find the speed of the water coming out of the holes in the shower head, you can use the equation for the continuity of fluids. This equation states that the mass flow rate of a fluid is constant. In other words, the amount of water flowing through the pipe should be the same amount flowing through the holes in the shower head.

First, you will need to gather the necessary information such as the diameter of the pipe, the number and diameter of the holes in the shower head, and the speed of the water in the pipe (Xm/s).

Next, you can use the following equation to find the speed of the water coming out of the holes in the shower head:

V = (Xm/s * (pi*(pipe diameter/2)^2))/(number of holes * (pi*(hole diameter/2)^2))

This equation takes into account the conservation of mass and accounts for the decrease in area as the water flows through the smaller holes in the shower head.

By plugging in the given values, you can calculate the speed of the water coming out of the holes in the shower head. Keep in mind that this calculation will give you an average speed, as the speed of the water may vary slightly due to factors such as pressure and turbulence.

I hope this helps! Let me know if you have any further questions. Happy showering! :)
 
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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
