OIL and WAter separation.

[Vaione]

hey i want to find how much amount of oil and water in bucket. ??? means how much oil and how much water. i know total amount of material. i have diameter of bucket. anyone can help me?

You know the volume, do you know the mass?
You know the density of water.
Do you know the density of the oil?
If you know what the oil is, then you can probably get close enough with an approximation for the oil density.
If so, because it is an additive property so the math should present no problems.

thanks. but can u explain little bit more. means give me a balance equation.

Sum of parts=Total
You can figure out your exacts.

Just an addition to JMW's advise. If you don't know the mass, use a smaller container, e,g a tin can,
-measure its weight/ mass, and dimensions. Pour the liquid-mix to half or full to the brim, measure its weight, -deduct from can's mass= liquid mass in can.
-divide container volume to can's volume per mass of liquid= total mass of liquid.
- density of water (known), density of type of oil(you can find from perry's handbook), the rest is maths.
Now I got a question for all in the Petro-world, I 'm a Chemi looking to work for either consulting or refinery, (my experience is 14 years in Semi-conductors, design, manufacture etc- same instrumentation, piping, except we use mostly vacuum, oil industry uses positive pressure. Any suggestions, pointers, recommendations, etc, etc.

tHANKS RICKY. I GOT IT NOW. SORRY BUT I M WORKING IN REFINERY FOR LAST 6 MONTHS. SO NOT THAT EXPERIENCED TO ADVICE YOU. BEST OF LUCK FOR JOB SEARCH

There is a catch.
If the density of the oil is close to that of water, you will have to use another method.

I have to say, and I may be guilty of misinterpreting your enquiry, that I thought you wanted to work out the water content by some simple means.
However, if you want to know the water in the oil by any means, not necessarily from the geometry of the bucket etc,
I'd suggest you might want to send a sample out to a lab.

This is a standard test conducted by SGS, DNV Petroleum Services, ViswaLab etc.

You may find that this is not an expensive test and is probably cheaper than you spending a lot of time at $x per hour trying to solve it and not getting your other work done.

If it is a common requirement then you may need to look at what laboratory grade tests are available in your on-site laboratory or consider either online testing with an oil in water monitor or a good offline test such as from Kittiwake

This is commonly used with fuel oils and lubricants where the water content is in the range upto 1-2% I guess.

COOL. HEY UR TALKS MAKE SENSE IF LAB TEST IS CHEAPER THEN MY HOURLY RATE THEN WE HAVE TO GO WITH LAB. HEHE. BUT STILL I WILL GIVE A SHOT IN WEEKEND WHEN I WILL AT HOME. THANKS FOR UR CONCERN.
