If I have a container or any other equipment . I know the density of the fluid inside the container . I know the weight of the fluid inside the container ( 100% full) . I know also the density of material !

 

In this case , can I estimate the weight of container itself ?

hi ,

The simplest  way should be to weight the empty  Container (truck scale or weight bridge)!

my 2 cents

Hi,

When you know the weight of the fluid and its density , you can calculate the volume of the fluid and the vessel.

Having known the rules of thumbs , depends on the vessel or tank and its orientation ( horizontal or vertical) you can take a ratio between its diameter and length ( height) , then solve the volume equation of the cylinder in term of one variable ( D or L) and obtain it, then by considering the thickness of the metal sheet, You can estimate the volume of the own vessel which is the multiply of peripheral area and thickness.

Now, having the approximate volume of the vessel sheet and density of the metal you can estimate the weight of the vessel.

 

W_fluid/Ro_fluid= V_fluid = V of the tank

 

For vertical Vessel L/D =1.5 so L=1.5 D

 

V = pi* D²/4 * L = 1.5 Pi*D³/4 , So D is obtained and consequently L is obtained

Area of vessel = 2* ( pi*D²/4) + pi*D*L

thickness to be estimated , for instance is 10 mm ( depending on the MAWP, working pressure )

So the Volume of the metal sheet of the tank = Area*thickness

Weight of the empty tank = Volume of metal * Ro_metal

 

hope it is useful

No.
