The water flowing through a 1.7 cm (inside diameter) pipe flows out through three 1.2 cm pipes. (a) If the flow rates in the three smaller pipes are 23, 19, and 12 L/min, what is the flow rate in the 1.7 cm pipe? (b) What is the ratio of the speed of water in the 1.7 cm pipe to that in the pipe carrying 23 L/min?
