The ratio of the density of an object or substance to the density of pure liquid water is known as A The buoyancy force on an object is equal to the product of the fluid density, the acceleration due to gravity and the submerged of the object. volume The pressure is difference in pressures across a boundary or the difference between the pressure at some point and the pressure at some reference point. A The incompressible guage pressure fluid phase is the phase.

3. Water is flowing through a steel pipe from a water tank to a garden, the pipes it flowing in frequently change size. Water is flowing at 4m/s in a tube with a diameter of 200mm. The tube gradually increases in size to a diameter of 1.2m, and then gradually decreases to a diameter of 900mm. Neglecting any energy losses due to friction and pressure changes, what is the speed of the water when it reaches out the tube diameter of 900mm?

3 A hotel builds a water (1.00 g/cm) fountain that is fed by a din = 14.9 cm diameter cylindrical pipe that carries water horizontally hbelow = 8.92 m below the ground. The pipe turns upward and eventually fires water out of the = 6.78 cm diameter end of the cylindrical pipe, which is located habove = 1.72 m above the ground, with speed Vout = 33.2 m/s. What gauge pressure is required in the underwater horizontal pipe for this fountain? dout Vout t habove h below O Vin din 7.24 atm 4.18 atm 6.24 atm 6.47 atm mop <

Three glass containers containing water of the same temperature have different shapes and thickness. The distance between the top surface of the water and the bottom of each glass container is the same. Which of the following statements correctly characterizes the pressure at the bottom of the glass containers? (explain why) 2 3 a. Pressure at the bottom of all glass containers is the same. b. Pressure at the bottom of (2) and (3) are the highest because they have the same volume. c. Pressure at the bottom of (2) is the highest because it is wide. d. Pressure at the bottom of (1) is the highest because it is narrow. e. Pressure at the bottom of (3) is the highest because it is vertically aligned.

An airplane is pressurized with air to 650 mmHg. a. If air is 21% oxygen, what is the partial pressure of oxygen on the plane?  b. If the partial pressure of oxygen drops below 100 mmHg, passengers become drowsy. If this happens, oxygen masks are released. What is the total cabin pressure at which oxygen masks are dropped?
