Pipe size vs flow rate
 

Hi,

I have been very confused over the relationship between flow rate and
pipe/tube size. So I thought I would ask the group to see if anyone could
explain it.

For the sake of this discussion -- let's eliminate the pump (just assume a
pump that is constant and it rated at 1000 gph at 1 ft lift). Let's also
eliminate friction over distance (assume distance is "short" enough that
it become negelagable).

Thus let's just look at what the effect of going from 1/2" tubing to 3/4"
would have (for example). Let's also consider the situation of going from
3/4" to 1/2" back to 3/4" (again, let's not worry about distance -- at
this point)


Thanks for the info
