Mar 23, 2013 · T = s* (W/D^2)*V^2. To empirically determine the value of s one only needs to rearrange the equation for s: s = T*D^2/ (W*V^2) and plug in the values for the characteristics of naval guns and with published values of T. If this is the correct formulation for the USN empirical penetration formula, then s should the constant for all guns.

• Formula for Caloric Intake |

Jun 24, 2019 · To burn 3,500 calories you should look at a span of days or weeks ⁠— it won't happen in one day. If your total calorie expenditure is 2,000 per day and you eat 1,500 calories per day, you're burning 500 calories per day. Over seven days, that's 3,500 calories or one pound of fat. The reverse is true if you want to gain weight.
