Calculating Volume of Water Flow From a Pipe & Sprayer

AI Thread Summary
The discussion revolves around calculating the volume of water flow from a pipe connected to a sprayer with multiple holes. The pipe has an area of 4 cm² and a water speed of 2.5 m/s, while the sprayer has four holes, each with an area of 0.5 cm². The initial calculations suggest a total flow rate of 60 liters per minute, but the poster's division of this volume by the number of holes leads to an incorrect conclusion of 15 liters per hole. Participants in the thread express confusion and provide support, indicating a need for clarification on the calculations. Ultimately, the poster seeks help to identify the mistake in their reasoning.

Homework Statement


A pipe has area 4 cm2 and is connected to sprayer that has 4 holes each of 0.5 cm2. If the speed of water in pipe 2.5 m/s, the volume of water that comes out from each of the holes in 1 minute is ... liters
a. 0.1
b. 0.6
c. 1
d. 6
e. 10

Homework Equations


A1v1=A2v2

Q = V/t = Av

The Attempt at a Solution


Q = Av = 4 cm2 x 250 cm/s = 1000 cm3/s

V = Q.t = 1000 x 60 = 60 000 cm3 = 60 liter

V in each holes = 60 / 4 = 15 liters ?

My answer doesn't even close to the choices...:cry:

Where is my mistake? Thanks

Weird, I agree with your answer.
 
I also agree.
 
I agree with Redbelly98 but disagree with ashishsinghal.
 
okay, that's funny.
 
lol, that's really funny

thanks for all your help guys :)
 

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'

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...
