GRAVIMETRIC DENSITY OF PRODUCTS OF

GRAVIMETRIC DENSITY OF PRODUCTS OF EXPLOSION
in. of water at this temperature weighs 62.35 lb, and therefore I lb of water bulks 1728+62.35=27.73 cub. in.
Thus if a charge of P lb of powder is placed in a chamber of volume C cub. in., the

Sometimes the factor 27.68 is employed, corresponding to a
density
  of water of about 62.4 lb per cub. ft., and a temperature 12 C., or 54 F.
With metric units, measuring P' in kg., and C in litres, the G.D. =P/C, G.V. =C/P, no factor being required.
From the Table I., or by quadrature of the
curve
  in fig. 9, the
work
  E in foot-tons realized by the expansion of I lb of the powder from one
gravimetric
  volume to another is inferred; for if the
average
  pressure is p tons per sq. in., while the
gravimetric
  volume changes from v-80v to vZAv, a
change
  of volume of 27.73 AV cub. in., the,
work
  done is 27.73 p w inch-tons, or
(7) DE=2.31 pOv foot-tons;
and the
differences
  AE being calculated from the observed values of p, a summation, as in the ballistic tables, would give E in a tabular form, and conversely from a table of E in terms of v, we can infer the value of p.
On drawing off a little of the gas from the explosion
vessel
  it was found that a gramme of cordite-gas at o C. and standard atmospheric pressure occupied 700 CCs., while the same gas compressed into 5 ccs. at the temperature of explosion had a pressure of 16 tons per sq. in., or 16X2240147 =2440 atmospheres, of 14.7 lb per sq. in.; one ton per sq. in. being in round numbers 150 atmospheres.
The
absolute
  centigrade temperature T is thence inferred from the gas equation
(8) R = pv/T = 001273,
which, with p=2440, v=5, p0-i, v0=700, makes T=4758, a temperature of 4485 C. or 8105 F.
