A steel pipeline 152-mm (6.0-in) diamenter with a wall thickness of  6 mm (0.24 in) extents 1,000 m (3,280 ft) between two reservoirs as show below. Compute the steady-state flow rate in the pipeline for h1 = 10.0 m(32.8 ft) and h2 = 50 m (164 ft), neglecting minor loses. If a valve in the pipeline at the lower reservoir is suddenly closed, compute the time that it will take the pressure wave to travel from the valve to the upper reservoir and back to the value.
