Question: A pump at one end of a horizontal pipe maintains a pressure that is 2.3 x 103 Pa. above atmospheric pressure as it pumps water into the pipe with speed of 2.7 m/s. The water emerges from the other end of the pipe, which is open to the atmosphere. If the radius of the pipe is 1.6 cm at the input end, a. what is its radius at the output end? and, b. what is the speed of the emerging water?
