It is defined as the pressure exerted by a column of water of 1 inch in height at defined conditions. At a temperature of 4 °C (39.2 °F) pure water has its highest density (1000 kg/m 3). At that temperature and assuming the standard acceleration of gravity, 1 inAq is approximately 249.082 pascals (0.0361263 psi). [2]
The Mk IX/X guns succeeded the BL 9.2-inch Mk VIII naval gun and increased the bore length from 40 to 46.7 calibres, increasing the muzzle velocity from 2,347 to 2,643 feet per second (715 to 806 m/s).
