Re: Text Height
If you can explain in which calculator do you have problem, maybe I can fix it next version.

Re: decanting one tank into another
Here is how you can start: Pressure drop in pipe due to friction is: Dp=rho * f * L * V^2 / (2 * D), or (A) Dp = 8 * rho * f *L * Q^2 / (D^5 * pi^2); where is: (B) Dp = rho * g * (H - Dh); - available energy due to level difference if both reservoirs are on atmospheric pressures (Dh - is the change ...

Re: decanting one tank into another
This is non-steady flow problem for which differential equation should be written.
I will try to provide one later today.

Re: how to calculate flow-rate and drop pressure on branch pipe.
Step 1. It is similar like in loop, but you have to know (or make an assumption) the pressure (head) on the start of the branch and at the end of the branch and based on pressure (head) change from start to the end of branch you can calculate the flow. Step 2. Now that calculated flow is influencing...

Re: Determining Air flowrate of air pump
Estimated maximum flow rate can be find if you devide motor power with pressure change. Also, energy losses should be taken into account, so flow rate is 10-20% smaller.
But if you don't know pressure, than it is difficult to know.

Do you know the pressure that is in?
