How to calculate water from storage tank to small tank?

AI Thread Summary
To calculate the water flow from a 10,000L tank using Torricelli's formula, the velocity can be determined with v=√(2gh), where h is the height of water. For flow rate, the equation Q=Av is used, with A representing the cross-sectional area of the pipe. When multiple tanks are involved, such as three 10,000L tanks draining into a 6-inch main pipe, the individual flow rates from the 2-inch pipes can be summed to find the total flow into the main drain. The flow speed will remain consistent, but the total volume will depend on the combined flow rates from all tanks. Accurate calculations require considering the capacity and configuration of the entire system.

I have a 10,000L water tank (size 3.5m Dia x 1.0 m H) connected to 2 inch pipe (bottom of the tank). How do I calculate the speed/volume of the water flow out from the tank?

You could use Torcelli's formula (from conservation of energy) to get v=√(2gh)

and then if you wanted the flow rate you'd use Q=Av where A = cross-sectional area of the pipe.
 
Thank You rock.freak667,

I checked the Torcelli's formula and it helps. However, using this formula. Can I calculate the water flow if it involve more that 1 tank?

For example:
I have "THREE" 10,000L water tank (size 3.5m Dia x 1.0 m H), each connected to 2 inch pipe (bottom of the tank) and share the same main drain pipe (6 inch). All three tank will flow from the 2" pipe to 6" main drain pipe and finally enter a storage tank. Will the flow/speed still be the same and I just change the Q=Av (A- from 2" pipe to 6" pipe) for the water flow?

TQ in advance.
 
If you want the water flow for the 6" drain pipe then you'd have to add the flows together I believe.

However I could be wrong as I've not done fluid related problems in for a few years.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
