The question is whether or not a progressive powder, if all burnt in a gun, and the
gases produced have gained mechanical and thermal equilibrium by the time the
projectile reaches the muzzle, will give as great a muzzle velocity, weight for ...

instantaneously, and suppose for the sake of simplicity, in lieu of other gas, that
gas from just the same small weight of powder (expanded against pressure)
already fills the powder chamber. The pressure of the last may be represented
above ...

In other words, the general equation is true at any point if w, the weight of powder
burned and in equilibrium, becomes constant at that point. We assume, in
mathematically treating this subject, that each elementary portion of the powder
gas ...

In finding the velocity due to powders of the same material, they use for any gun a
certain factor of effect, which they multiply into the theoretical velocity (according
to their method) due to the weight of the charge. They tacitly assume as a ...

They are similarly loaded when the volumes of powder chambers and the
weights of the charges and projectiles vary ... in the two cases, when w equals
Wthe full weight of charge ; that is, when all the powder is burnt, as with quick
powders.

Sivu 516 - Thus with the year Seasons return, but not to me returns Day, or the sweet approach of even or morn, Or sight of vernal bloom, or summer's rose, Or flocks, or herds, or human face divine; But cloud instead, and ever-during dark Surrounds me...
Sivu 523 - Kent. Vex not his ghost. O, let him pass! He hates him That would upon the rack of this tough world Stretch him out longer.
Sivu xxiv - The President, or, in his absence, the Vice President, or, in the absence of both, any member of the Council, shall preside at all meetings of the Society and of the Council.
Sivu 523 - One hundred and thirty-second day. Too weak to carry the bodies of Lee and Kaack out on the ice. The Doctor, Collins and I carried them around the corner out of sight. Then my eye closed up.
Sivu 334 - Though the strain'd mast should quiver as a reed, And the rent canvas fluttering strew the gale, Still must I on; for I am as a weed, Flung from the rock, on Ocean's foam to sail Where'er the surge may sweep, the tempest's breath prevail.
Sivu 523 - October 22nd. 132nd day. Too weak to carry the bodies of Lee and Kaack out on the ice. The Doctor, Collins and I carried them around the corner out of sight. Then my eye closed up.
Sivu 270 - ... and the Beebe-McLellan surf-boat, from the names of the persons who devised the modifications which characterize them, are the only ones furnished to the stations in recent years. They are all constructed of white cedar with white-oak frames, and their dimensions are from 25 to 27 feet in length...
Sivu 91 - the evidence of the superiority of the gun, and the development of the efficacy of the ram and the torpedo had deprived us of sufficient excuse of late years to continue to fight the losing game of armour against guns.
Sivu 351 - We find that a long stretch of coast is not sufficient, though necessary, to make the population of a country a seafaring nation. When the Romans invaded Britain, the Brits had no fleet to oppose them. We do not until a later period meet with that love of the sea which is so characteristically English : — not before the gradual absorption of the earlier inhabitants by a blue-eyed and yellow-haired seafaring people who succeeded in planting themselves and their language in the country.
Sivu 257 - Qualities as a rowing boat in all weathers 20 Qualities as a sailing boat 18 Qualities as a sea boat ; as stability, safety, buoyancy forward for launching through a surf, &c 10 Small internal capacity for water up to the level of the thwarts . Means of freeing boat of water readily... 8 Extra buoyancy; its nature, amount, distribution, and mode of application 7 Power of self-righting 6 Nos.
