Many small sailboats use a passive bailing system: there is a plug in the bottom of the boat that can be opened to drain water out of the boat. This works only when the boat is moving, because only then is the pressure under the boat less than air pressure, by Bernoulli’s equation. Consider a boat whose bailing plug is located 3 cm below the surface of the water. What is the minimum speed the boat must have so all the water drains out of the boat?
Homework Answers
minimum speed the boat must have = sqrt(2 * g * H)
= sqrt(2 * 9.8 * 0.03)
= 0.7668 m/sec
=> minimum speed the boat must have so all the water drains out of the boat = 0.7668 m/sec

Draining a tank A cylindrical water tank has a valve at the bottom. When the valve is opened, the water drains out, and rate at which the water flows out is proportional to the fill level because the pressure in the tank is proportional to the mass of water in the tank. Therefore the decrease of mass in the tank is given by , where m is the mass of water in the tank and α is a constant. (a)...

A diver is located 63 m below the surface of the ocean (the density of seawater is 1.025 kg/m3). To raise a treasure chest that she discovered, the diver inflates a plastic, spherical buoy with her compressed air tanks. The radius of the buoy is inflated to 0.41 m. If the treasure has a mass of 215 kg, what is the acceleration of the buoy and the treasure chest when they are tethered together and released? The chest is 22...
