Foot Pounds of Energy Calculator, Formula, Foot Pounds of Energy Calculation

Foot Pounds of Energy Calculator:

Enter the values of Mass of Grains Mg_(grains) & Bullet Speed BS_(ft/min)   to determine the value of Foot Pounds of Energy E_{(foot-pounds)} .

Foot Pounds of Energy Formula:

The Foot Pounds of Energy E_{(foot-pounds)} in foot-pounds is Equal to the Mass of Grains Mg_(grains) in grains and Multiply the Bullet Speed BS_(ft/min) in feet per minute is squared and then Divided by the value of 450437.

The Formula of Foot Pounds of Energy can be written as,

E_{(foot-pounds)} = Mg_(grains) * BS²_(ft/min) / 450437

Here,

E_{(foot-pounds)} = Foot Pounds of Energy in foot-pounds

Mg_(grains) = Mass of Grains in grains

BS_(ft/min) = Bullet Speed in feet per minute

Foot Pounds of Energy Calculation:

1) Calculate the Foot Pounds of Energy and given for the Mass of Grains = 8grains, Bullet Speed = 1000ft/min.

Answer

E = Mg * BS² / 450437

E = 8 * 1000² / 450437

E = 17.76 foot-pounds.

2) Calculate the Bullet Speed and given for the Mass of Grains = 8grains, Foot Pounds of Energy = 17.76 foot-pounds.

Answer

E = Mg * BS² / 450437

17.76 = 8 * BS² / 450437

BS = 1000 ft/min.
