Requesting Help with Water Flow rate problem

RedCrowsgt

Hi all
I am trying to calculate the flow rate of water through a 6mm pipe as i am working on a water wheel project with some friends

the information i have to offer is this

-i have a 25L water container
- Height: 370mm
- Width: 270mm
- Length: 350mm

- there is a 6mm pipe attached 90Âº to the base and flush with it

-the top of the container is open to the atmosphere

i am hoping someone here can help me learn how to work this out
thanks for any help offered

as long as $$\displaystyle \rho$$ acts upon it , then $$\displaystyle \;$$ $$\displaystyle p=\rho_a -\rho$$

sorry but we have tried to work out how that will help i a little unsure is there any chance you could explain with a touch of detail or illumination on what each factor in that equation is ?

you'll need to use Bernoulli equation to calculate the flow, you can simply use v = sqrt(2*g*H) this one will give you the flow velocity at the connection for given water head "H", however, this will be time dependent since you're using a tank of limited capacity. it will also be inaccurate if you tried to verify your calculations by measuring the flow at the end of the pipe, in this case you'll need the pipe length and a friction formula (darcy-weisbach for example).
