While out on your boat you spot a spherical vessel (10 ft diameter) on the bottom of the ocean. The sphere is too heavy/large to bring into your small boat (length=2.5 m, width=1.5 m and height=1 m), so you decide to tow it in. Your boat has a 20 hp motor. Assuming you operate your boat at maximum power, how long does it take to tow the object back to shore (distance 2 miles) if your boat has a coefficient of drag Cp=0.4. 1 Assume that the stress on the bottom of the boat can be ignored and recall that for turbulent flow for a sphere Cp=0.44. The wind is luckily not blowing that day. The air is at 1 atm and 15°C and water at 25°C. 20 hp

A closed tank 2 m deep, 1.8 m wide and 3.5 long has been filled with gasoline of S= 0.8 upto a depth of 1.6 m. Calculate the acceleration which may be imparted to the tank in the direction of its length so that bottom front end of the tank is just exposed. Also calculate the net horizontal force acting on the tank sides sides and show that this is equal to force necessary to accelerate the liquid mass.

Suppose that one such tank is cylinder shaped, 50ft high with a radius of 20ft. If we assume that water is pumped out of the tank via a pipe directly on top of the tank and that the tank is filled to a depth of 30ft, how much work (in ft-lbs) would be done by a pump to empty the tank? You may take the density of water to be 62.4 lbs/ft3
An open cylindrical tank 60 cm in diameter and 60 cm high is 2/3 full of water. If the tank is rortated about its axis at the center, a.) what is the maximum speed it can have without spilling? b.)what speed must it have so that there is no water within 15 cm. from the axis of rotation? At this speed, how much volume is spilled?
2-liter soda bottles do not have flat bottoms. A bottle can be approximated as a cylinder filled from the bottom up to 0.26-m high with a hemispherical space of 10-cm-diameter underneath. If you treat the soda as having the density of water, what is the force in N of the soda on the curved bottom of the soda bottle?
