The chemical formulae of mineral oil used in transformers is
C12H10-xClx, where x = 1-10(poly chlorinated bi phenyl)

Answer / anand

it does not have any typical formula. it is basically
obtained from the vacuum distillation of the atmospheric
residue.

Answer / b srinivas

chemical name:

Hydrotreated light napthanic distillate
(or)
chlorinated derephyl

oil name : synthetic oil

Answer / javed

di floro di chloro ehtyl benzene is the chemical name

Answer / dhanashree

As mineral oil is mixture of many hydrocarbon compounds
like alkynes, cycloakanes and aromatic hydrocarbon. Hence
it has no specific formula.

Answer / lakshmareddy

it does not have any typical formula. it is basically
obtained from the vacuum distillation of the atmospheric
residue.because of above reason it does not have any
chemical formula.

PROCESS CONTROL - EXAMPLE 6.2 : A stream with volumetric flow rate Q enters a cylindrical tank and a stream with volumetric flow rate q exits the tank. The fluid has a constant heat capacity and density. There is no temperature change or chemical reaction occurring in the tank. Develop a model for determining the height of the tank, h. Let V is the volume, A is the cross sectional area, r is the density, m is the mass, where V and A are for the tank, r and m are for the fluid. The rate of mass of fluid accumulation, dm / dt = (Q - q) r. Prove the model to be dh / dt = (Q - q) / A.

POLYMER ENGINEERING - QUESTION 24.1 : The molecular weights M in kg / mol of 3 different monomers a, b and c in a polymer are Ma = 14, Mb = 16 and Mc = 18. The fraction of polymer chain X of 3 different monomers a, b and c in a polymer are Xa = 0.5, Xb = 0.3 and Xc = 0.2. (i) Calculate number average molecular weight by using the formula Ma Xa + Mb Xb + Mc Xc. (ii) Calculate weight average molecular weight by using the formula (Ma Xa Ma + Mb Xb Mb + Mc Xc Mc) / (Ma Xa + Mb Xb + Mc Xc). (iii) Calculate the polydispersity by using the answer in (ii) divided by answer in (i). (iv) If the molecular weight of repeat unit is 12, calculate the degree of polymerization by using the formula (Ma Xa + Mb Xb + Mc Xc) / (molecular weight of repeat unit).
