In order to form a stream of bubbles, air is introduced through a nozzle into a tank of water at 20°C. If the process requires 4.0 mm diameter bubbles to be formed, by how much the air pressure at the nozzle must exceed that of the surrounding water? What would be the absolute pressure inside the bubble if the surrounding water is at 100.3 kN/m2?Take surface tension of water at 20°C = 0.0735 N/m. *

In order to form a stream of bubbles, air is introduced through a nozzle
into a tank of water at 20°C. If the process requires 4.0 mm diameter
bubbles to be formed, by how much the air pressure at the nozzle must
exceed that of the surrounding water? What would be the absolute
pressure inside the bubble if the surrounding water is at 100.3 kN/m2?Take
surface tension of water at 20°C = 0.0735 N/m.
