A centrifugal pump is used to pump water between two large open tanks through 30m of 20cm diameter pipe. The pipeline contains four regular flanged 90o elbows, a check valve and a fully open globe valve (find each KL in the book). Other minor losses are negligible. Assume the friction factor f = 0.02 for the 30m section of pipe. If the static head (difference in height of fluid surfaces in the two tanks) is 9m, determine the expected flow rate.
