See post #5 in this thread:

In particular, the last paragraph explains how to deal with elliptical rather than hemispherical endcaps. You can program the equation in Excel.

Re: Volume of horizontal cylindrical tank

tank diameter = 3000mm
Tank length =10000mm
at 0.5 of height of cylender what is volumeof liquid

Total capacity is (pi/4)*d²*l = 0.785*(3 m)²*(10 m) = 70.69 m³

At half height, capacity is 1/2 this (not true at other heights) so 35.34 m³ (35340 L).

Re: Volume of horizontal cylindrical tank

Sir,
We have Furnace oil Storage tank (ellipsodial Tank)
Tank Diameter : 240CMS, Tank Length (Cyl. Portion):5537
Both ends depth is 26cm each side. solvent having 0.79 specific gravity to be store
Can you let me know the total volume if liquid is filled to a depth of 240cms, and i need dip stick reading at every centimeter.

Regards,
kaushik bhatt.

Depends on the contents. For fuels like gasoline and diesel, the tank is "dipped" from the top with a long calibrated rod or dipstick. Some tanks have glass sight-tubes on the end to show liquid levels (valves should be installed in case the tube breaks)

For pressurized liquids such as propane, you can't use dipstick, and sight tube may be a problem too.

You can mount some kind of sensor with a float or other means of sensing the liquid level. These usually require some calibration, and tank may need to be emptied for installation.

Re: Volume of horizontal cylindrical tank

Dear Sir,

Length is 2500 mm and diameter 1500mm of the horizontal cyclindrical tank give me the readings of the volume of the liquid (sulphuric acid) from 1 inch to 60 inch.
pls give the answer soon as possible

Re: Volume of horizontal cylindrical tank

Folks,

Re the solution below- I actually need the inverse function, whereby I can calculate the depth measured along a vertical diameter as a function of the occupied volue of the horizontal tank.

(I am pumping fluid into the tank at a known rate, and I need to measure how fast the level rises)

I haven't touched algebra of this complexity in over 30 years, so I am a bit rusty (Certainly rustier than my tank!) I tried, but hit the wall.

Can anyone help?

Thanks!

My help will be limited. The equation relating s and V in Roy's note can't be explicityly solved in the other direction, only from s to V. It can be solved by iterative approximation methods such as Newton's method (Trust me: if you algebra is rusty you don't want to go there)

But look at the changes per 100 mm at topr or bottom vs the middle. At top and bottom, only 347 L are required to fill it the last (or first 100 mm), but in the middle, between 1100 and 1200 mm, it is 1265 L/100 mm

For your tank, construct a table such as the above and look at the amounts required to fill a given fraction of the depth at top or bottom vs middle. I assume you are worried about overflow, and the worry is valid. The last little bit of depth fills rapidly.
