Question 2 A spray bottle is used to spray small droplets of carbon tetrachloride. Determine the pressure difference between the outside and inside of a droplet of carbon tetrachloride (R = 100 µm) while in air (T = 20C).

Q1.A

Determine the gage pressure at the water's surface in the tank below. The specific gravity of acetylene tetrabromide is 2.95. 1.9m Air Water Radius 1.1m + 0.4m 2.1m Acetylene Tetrabromide Open to the Atmosphere 1.5m 1.8m

Question 6 Which of the following statements regarding the formation and collapse of vapor bubbles in a liquid during cavitation is correct? Vapor bubbles are formed when the fluid pressure drops below the vapor pressure and collapses when the fluid pressure goes above the bubble pressure Vapor bubbles are formed when the fluid pressure drops below the vapor pressure and collapses when the fluid pressure goes below the bubbie pressure Vapor bubbles are formed when the fluid pressure goes above the vapor pressure and collapses when the fluid pressure goes below the bubble pressure d. Vapor bubbles are formed when the fluid pressure goes above the vapor pressure and collapses when the fluid pressure goes above the bubble pressure
