A golf course sprinkler system discharges water from a horizontal pipe at the rate of 7100 cm3/s c m 3 / s . At one point in the pipe, where the radius is 3.85 cm c m , the water's absolute pressure is 2.10105 Pa P a . At a second point in the pipe, the water passes through a constriction where the radius is 2.10 cm c m .

What is the water's absolute pressure as it flows through this constriction?
