A handheld air pump (diameter = 5 cm, length 20 cm) can be used as an atomizer (hole diameter 0.3 cm) to generate a fine mist of paint or pesticide by forcing air at a high velocity through a small hole and placing a short tube between the liquid reservoir (open to the atmosphere) and the high-speed air jet whose low P drives the liquid up through the tube. The vertical distance between the liquid level in the tube and the hole is 10 cm. If the atmospheric conditions are 20C and 95 kPa, determine the minimum piston speed in the cylinder during pumping to initiate the atomizing effect. -20 cm- 0.3 cm 5 cm Air Liquid rising 10 cm
