Power Factor Estimator

Power Factor Calculator will calculate:
- Power Factor,
- Average Velocity,
- Velocity Spread.
Also would be shown the minimum and maximum velocity from the Velocity Table data.
To calculate the Power Factor you have to enter the Weight of projectile in grains.
Then add the velocities(in ft/s) to the table by specifying the velocity, and pressing the "Add" button.
Thereafter all velocities was added to the table, press a "Calculate" button to perform the calculations.
You can remove the particular value of velocity by swiping left. Or clear all Velocity Table by pressing the "Clear" button.
