Ahandheld bicycle pump can be used as an atomizer to generate a fine mnist of paint or pesticide by forcing air at a high velocity through a small hole and placing a short tube between the liquid reservoir and the high - speed air jet. The pressure across a subsonic jet exposed to the atmosphere is nearly atmospheric, and the surface of the liquid in the res ervoir is also open to atmospheric pressure. In light of this, explain how the liquid is sucked up the tube,
