Question

c) Consider a U-tube whose arms are open to the atmosphere. Now equal volumes of water and
light oil (dersity=49.3 kg/m?) are poured from different arms.
Air
Oil
Water
30 in
A person blows fromthe oil side of the U-tube until the contact surface of the two fluids mmves to
the bottomof the U-tube, and thus the liquid levels in the two arms are the same. If the fluid height
in each am is 30 in, determine the gage pressure the person exerts onthe oil by blowing.
