Extracted text: 56. A pump is operating in recirculation mode. At time zero, we close the bypass valve and simultaneously open the isolation valve to fill the initially drained sup- ply line. Use the data to find the time it takes to fill the supply line. Data: = 200 GPM, Lsupply Line = 1200 ft, Dsupply Line = 3 in.
