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.

According to Shockley equation, the I – V characteristic of a diode is approximated by I = IS [ exp (nVD / VT) – 1 ]. For silicon, let the reverse bias saturation current IS as 0.000000000001. If n is ideality factor with value of 1.5, VT as thermal voltage drop of 0.026 V at room temperature, what is the value of current I that passes through the silicon diode in the heater of evaporator when the forward voltage drop VD = 0.026 V? Please take note that exp is the exponential function with e(1) = 2.718, e(2) = 7.389.

QUANTUM COMPUTING - EXAMPLE 32.3 : A system of linear congruences consists of 3 equations : X ≡ 1 (mod 3), X ≡ 3 (mod 5), X ≡ 4 (mod 6). X has positive values. (a) List the values of these equations from 1 to 35. Then find the minimum value of X. (b)(i) Find the least common multiple (LCM) of b = 3, 5 and 6 where X ≡ a (mod b). (ii) If b - a has the same value of all equations above, then X + (b - a) is divisible by LCM. Find the value of minimum value of X via LCM division.

Question 41 - According to Raoult's law, the pressure when vapor is completely condensed, P = x(1) P(1) + x(2) P(2) ... + x(n) P(n) when x(1), x(2) ... x(n) are the mole fractions of component 1, 2 ... n and P(1), P(2) ... P(n) are the vapor pressures of component 1, 2 ... n. A vapor at 74 degree Celsius containing 70 mole % water and 30 mole % ethanol is to be completely condensed. At the temperature of 74 degree Celsius vapor pressure is 0.38 atm for water and 0.97 atm for ethanol. What is the minimum pressure the compressor must be operated?
