Ball ReadingFlow Rate ( mL / min)Flow Rate ( L / min )
: Andrew Jay Hunter:

The program requires the user to enter values for ball readings and flow rates in mL/min. The values of L/min are automatically calculated and displayed for reference.

A maximum of 6 Ball Readings and Flow Rates may be entered. For fewer values simply enter zero in both the Ball Reading and corresponding Flow Rate field.21048.4277.35449741.71811.11.81112.52762.62.7626332373.237000000


: Andrew Jay Hunter:

The program automatically plots the data points and then provides an equation and graphical representation for a best fit line.

Mathematically this is represented by:Y=mx+b, with m representing the slope andb representing the y intercept. The y-intercept is a point where a line, curve, or surface intersects the y-axis. The x represents any variable the user wishes to evaluate.
