Homework Statement
An engineer is planning for a network of pipes to a residential tower containing 360 apartments each one of them consumes 0.05 liters/s of water what is the least possible pipe discharge for the main pipe in the network
if the fastest speed of discharge in the pipe is 4m/s then what is the least diameter possible that doesn't cause leaking
Homework Equations
J=Av=V/t
The Attempt at a Solution
I convert from liters to volume try to apply the law of course it doesn't work I have two variables
https://www.physicsforums.com/threads/pipe-discharge-and-diameter.860980/goto/post?id=5402647#post-5402647 my work:
360*0.05*10^-3/s=A*4
A=0.0045
0.0045=(d/2)^2*pi
d=0.07m. I think the 360 apartments are vital to solve this problem but I don't know where to use them
the diameter is 0.2m How do I get this answer?[/B]
