How to Calculate the Volume of Oil at Required Temperature

02/04/2013 8:25 AM

Dear All,

My client has given me Mass flow rate of Furnace Oil. For calulation Pipe sizing i converted it to Volume Flow rate by following method.

Density @ 15 Deg = 950 Kg/cm3

Total Flow = 39000 Kg/hr

Volume FLow = 39000/950 = 41.05 m3/hr @ 15 Deg

P1 V1/T1 = P2V2/T2

41.05/(273+15 Deg) = V2 / (273 + 115 Deg) (115 required temperature and pressure constant)

V2 = 44 m3/hr

Please advise me whether i have done correct or not.

My doubt is whether the gas law formula can be applied for Oils also??

Please clarify my doubt.

Regards

Rakesh Reddy

Maybe, maybe not, though it still comes out at 80mm pipe, whichever value is chosen.

The gas law does not apply.

If you make the effort to look at any book about oils you find a volumetric expansion coefficient which allows to correctly compute what you want. I have a secondary question : are you aware of the specific weight you mention ? It is 1 million times heavier than usual oils ! You should have written m^3 not cm^3!

The low for gases -as was already mentioned- applies for GASES not for liquids!
