To calibrate and compare the volumes obtained from image processing method it was used of current
method of measuring water displacement. This method was done in several ways that is one of the most
current uses of scaled cylinder which causes carelessness of measuring due to capillary action of water. Due
to this to decrease in this error, it was used of scaled cylinder, which its orifice diameter was large. Capillary
action of water is not more tangible in this scaled cylinder and the care of reading numbers was relatively
high. Schematic image of scaled cylinder has obtained in fig 1
