g A cylindrical tank, open at the top, of diameter 15 cm is filled with water to a height of 5 m. A pinhole is drilled into the side of the tank at a location that is 2.75 m below the surface of the water. According to Bernoulli's equation, find the velocity of the water emerging from the pinhole in m/s. Do not include units in your answer as Blackboard will not understand.
