Tank level Calculation 1

[mEng123]

Hey guys,

I have been given a task involves 3 tanks, 1 vertical and 2 horizontal, connected to each other. the vertical tank is supplying the other two similar size horizontal tank. I need to find out what would the level be in the vertical tank if the other two tanks are 90% filled. I know it is a fairly easy problem but i started getting confused when I am using Bernoulli equation. I already know what the 90% level in both tank would be and I already calculated the areas and volumes. I request advice or help on this issue!

You state you have calculated the 90% level and you bring up the Bernoulli equation. One has absolutely nothing to do with the other.

You basically have a Strapping problem. Go to the following website and download a workbook titled "Vessel Volumes".

This workbook will enable you to strap your vessels to whatever height of liquid you have.

Does the homework problem tell you if the tanks are connected by pumps , or by gravity-flow (open) lines?


Are both (output) tanks built on the same level and the same diameter and the same length? (you said they were similar size.) What is the type of head (flat, hemisphere, ellipsoid, etc) of the horizontal tanks?

What is the assumed "100% level" of the horizontal tanks based on? An overflowing tank, or is there some kind of vent space or dome in the top of the tank?

What was the initial volume of liquid in both tanks? Was that volume the same in both tanks?

It is all about volume calculations and nothing to do with Bernoulli's equation.
