r. H. Smith, ESQ:
SIR-To the questions you have pro-
pounded, have the honor to reply as
follows: i
Question 1-Can the same amount OF
light be obtained from an ordinary one
foot burner, using pure, rich petroleum
gas, when proper pressure is applied 70
effect a perfect combustion, as from an
ordinary five-foOt burner, with good
coal gas?
AnsWer-The rule for the flow Of &c ses
of different densities from given burner
ia as the square roots of the deRsities in
versely. Ordinary cosi-gas, OF sixteen
| candle power for five feet per hour lat
| the rate Of 80 candles for one FOOT has
| density OF AZ, the square root OF which
| is .648 The density Of q gas made from
| crude petroleum, as obtained from a
yield per gsllen of, say so cubic feet OF
gas, worth go candles for five feet Il give
| very low figures. so as to be on the safe
side), allowing 20 per cent. for tar ana
waste. is as follows: As the oil weighs
6. 66 pounds per gallon, 46o Beaume, we
get, throwing off 20 per cent, 5.35
| pounds Of gas per gallon, measuring 5O
| feet, which is 7.46 grains per foot OF gas.
AS air weighs IS grains per foot, the
duty must therefore be 746 .565, equal
| to ]. 80, the square root OF which is Is.
Therefore, the relative flows from one
foot burner must be in the ratio OF these
figures, LIS 6.48, or as l 1854. Now
five feet OF Oil-gas being worth % can
dies, 5 "a foot will be worth 6.77 candles
against one foot Of coal'gas worth $50
| cardles theoretically; therefore, the
light .given by oil.gas under the same
pressure from a one foot burner should
be double that from coai-gas. The ball
ance is more likely, however, to be still
more in favor OF the oil-gas small
burners, because the proper pressure re-
ferred to in the question is somewhat
greater, and the flow, therefore, larger.
Question 2-Whst is the related illu'
} minsting value of coal and pure oil
gases?
Answer-It is dependent on the vol
ume of the gas made from the oil, which
may be, according to the manipulation,
from 50 to 100 cubic feet OF gas per gal
lon, though the making Of the latter vol

is troublesome. The smaller volume
r may have an Illuminating value Oh

larger volume OF from forty to fifty can

8 worth sixteen candles.
7 Question 3-I5 pure oil gas more eX
1 plsosive than coal gas?
D AusWer-In some cases it must &c re

when leaking, on account OF the fac
g that much smaller vOllme OF il, say
only one-fifth as much is needed to form
i all explosive mixture with air. 1t csn
Il not be asserted, however, that whe
a such explosive mixtures are once forme
It they are practically more powerful
e the one case than in the other. AuOthe
e point is, that the weight of oil gas cause
it of rising to the ceiling, like coal gas, an
= explosive mixtures are hence formed

stead Of the upper parts. This, IN som
D cases, increases the danger (from explt
ding by contact with tires), and,
% o.her cases, decreases it from expiOnin
At by contact with lights). 1t is ditticu
J. to strike balance as a practical que,
"a ton, but do not think the difference
al the average number or distinc;lVeGess
r. explosions in the two cases, is likely
be important.
~ Question 4-Is oil gas, properly MAJ
ia ufactured, any more liable to clog up th
pipes than coal gas?
a. Answer-If the oil gas is made froI

ic observation proves that it is much LEI
