A water pipeline 3 m in diameter, 1000 m-long, has a steady discharge of 22 m³/s under a head of 160 m. If the gate at the end of the pipe is closed in 6 seconds, plot the water head at the valve for 15 seconds from the start of the closure, estimated at 1 s intervals. The velocity through the gate obeys V=kvvp, and the acoustic speed is 1000 m/s. Tabulate the amplitudes of F and f waves.
