What reading level is Smokeless Powder And Its Influence On Gun Construction book?
To quickly assess the difficulty of the text, read a short excerpt:
81. What is most important to note is that whilst the maximum pressure is considerably less with the B. N. Powder, although the work done is nearly 15 per cent, more, and the powder charges 40 per cent, less, the pressures are thrown so much further forward, that the B. N. Powder if fully utilised will require a very differently proportioned gun, one, namely, in which there is about the same strength behind the point of maximum pressure, but very much greater strength in front of it.
82. Taking... for instance the point g lt Fig. 2, at 110 inches from the muzzle, the pressure to be resisted will be 10 tons per square inch with the B. K powder, as against 5 J tons with the pebble.
83. It is quite true that this pressure may be reduced by reducing the charge of the B. N. Powder.
84. If, instead of firing with 33 * 08 Ibs. , the charge was reduced to 28 f 52 Ibs. , the velocity would be the same as that given by the 54 Ibs. Of pebble powder, and the maximum 28 SMOKELESS POWDEE.
pressure would be reduced to 14 tons per square inch.
