A 2300 m long pipeline leading from a large tank has a
diameter of 15 cm and thickness of 2.8 mm. When a discharge of 2200 L/min of
water was flowing the valve was suddenly closed completely. Sketch the
variation of the water hammer pressure with time at (i) the valve end, (ii) a
distance of 575 m from the valve and (iii) 57.5 m from the upstream tank.
