A hole with a radius of 0.1 mm is drilled into the bottom of a plastic box. What is the maximum height of water that can be added into the box before water will begin to run out the hole? The plastic is non-wetting and has a water contact angle of 108°
Homework Answers
height/diameter of hole =tan(contact angle/2)
height =diamter *tan(contact angle/2)
Height =height of plastic box-height
Height =height of plastic box-0.137 mm
