Question

A. just after the hole is made, what is the speed of the water as it emerges from the hole? (answer 4.45 m/s)

B. what is the ratio of this speed to the efflux speed if the top of the tank is open to the air?

C. How much time does it take for all the water to drain from the tank?

D. What is the ratio of this time to the time is takes for the tank to drain if the top of the tank is open to the air?
