Consider a U-tube whose arms are open to the atmosphere. Now equal volume of water and light oil (ρ=790 kg/m3) are poured from different arms. A person blows from the oil side of the U-tube until the contact surface of the two fluids moves to the bottom of the U-tube, and thus the liquid levels in the two arms are the same. If the fluid height in each arm is 102 cm, determine the gage pressure the person exerts on the oil by blowing.
