Explain briefly. a) Calculate the pressure difference between the two drops. The surface tension for water is 0.0728 N/m. b) 3. A microfluidic channel has a two openings as shown below, and is filled with water. Using the pipette, two spherical droplets, with the radius of 1mm and 5mm each, were put down at the openings. r=1mm r=5mm...
