Method of Calibration: Average Value Equation
n < 0.42 V = 0.2190 n +0.0153 m/s
0.42 < n < 3.73
V = 0.2459 n +0.0041 m/s
n > 3.73 V = 0.2508 n -0.0142 m/s
Starting Velocity = 0.025 m/s
Maximum Velocity = 5.000 m/s
Note: 'n' denotes the number of revolutions of the propeller per second
'V' is the water velocity in meters per second.
