Program that calculates drip parameters.

The calculations use the formula:

L=F*T/D

where
L: Amount of Liquid (ml)
T: Time period(min)
D: Drop factor(ghs/ml)
F: Flow rate (drops/min)

Fill all the parameters except one of the L,T,F and press 'CALCULATE' to calculate the missing parameter.Parameter 'F' can also be calculated using smartphone's camera or a timer by pressing the relevant button.
Measure Flow rate from camera.
If the flow rate is between (0.5 - 3) drops per second, it is possible to use camera to measure it. Press button 'GET FLOW RATE FROM CAMERA'. This will activate the camera. Hold the phone near the drip such a way that drops follow the red vertical line that appears on the screen. Tap on the screen and wait for 5 seconds for the recording. At the end of the recording the measured flow rate will be appeared on Flow Rate field. During recording the smartphone must be as steady as possible.
Measure Flow rate with timer
Press button 'GET FLOW RATE FROM TIMER'. The application can use a timer to measure the time between a number of drops (filled in 'Num of drops' field). Press 'START' and the first drop and 'STOP' after the last one. The calculated Flow Rate will appeared on relevant field.

By pressing sound button in main screen you can hear a beep in the frequency of the drop rate given in drop rate field, or in the calculated drop rate frequency. This can help to adjust the drop rate of the drip.
