A clear plastic tube with a diameter of 12cm and 110cm high is filled to the top with mercury. (density = 13.6 kg/m^3). There are three holes, all with a radius of 2 millimeters located 15cm from the bottom, 50cm from the bottom and 80cm from the bottom.

A) What is the velocity of the mercury coming out of the bottom hole?
B) What is the velocity coming out of the bottom hole?
C) What is the pressure at the bottom of the tube?
D) What is the flow rate of mercury coming out of the middle hole?
E) How long would i take (s) to fill a cylindrical container with a diameter of 8cm and a height of 6cm with the mercury coming out of the middle hole above?
Remember to use m/s and meters.
