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

Question
![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 CD=0.44. The wind is luckily not blowing that day. The air is
at 1 atm and 15°C and water at 25°C.
