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.

Consider a tank of rectangular cross-section partially filled with a liquid placed on an inclined surface, as shown in the figure. When frictional effects are negligible, show that the slope of the liquid surface will be the same as the slope of the inclined surface when the tank is released. What can you say about the slope of the free surface when the friction is significant
A rigid tank holds 20 lbm of air at a pressure of 20 psi and a temperature of 70°F. Increase the amount of air introduced into the tank until the pressure and temperature reach 35 psia and 90 degrees Fahrenheit, respectively. Calculate the amount of air that should be pumped or added into the tank.
aerodynamics: Determine the difference between the total pressure of an aircraft flying at sea level, and an aircraft flying at 5KM? Both have a velocity of 100m/s.
