Consider a U-tube whose arms are open to the atmosphere. Now equal volumes of water and light oil ( ρ = 49.3 lbm/ft 3 ) 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 m the two arms are the same. If the fluid height in each arm is 30 in, determine the gage pressure the person exerts on the oil by blowing.

A u_tube whose arms are open to the atmosphere. Now equal volumes of water and light oil. (density =49.4kg/m^3)are poured from different arms. A person blows from the oil side of the u_tube until the contact surface of the two fluid moves to the bottom u_tube, and thus the liquid levels in the two arms are the same .if the fluid height in each arm is 30in,Determine the gauge pressure the person exerts on the oil by blowing.
The maximum blood pressure in the upper arm of a healthy person is about 120 mm Hg.
If a vertical tube open to the atmosphere is connected to the vein in the arm of the
person, determine how high the blood will rise in the tube. Take the density of the blood
to be 1050 kg/m³. Food for thought: How do you experimentally measure blood density?
The pressure in a natural gas pipeline is measured by the manometer shown in Fig. with one of the arms open to the atmosphere where the local atmospheric pressure is 14.2 psia. Determine the absolute pressure in the pipeline
