QUESTION 22.1. A water hammer is a phenomenon caused by the sudden increase or decreasein fluid velocity which results in pressure fluctuations in a pipe.A common cause of the water hammer is rapid closure of a valve in apipeline. In order to minimise the pressure rise, the closure time of thevalve needs to be increased. If a pipe (K = 18.9 x 105 kPa) is laid for adistance of 1500 m, which of the following would be considered a gradualvalve closure time?(a) 1.3 seconds(b) 5 seconds(c) 2.18 seconds(d) All of the above 2.2. hich of the following is considered a minor friction loss in pipe system?(a) Slight changes in elevation(b) Shock losses due to a pipe contraction(c) Head loss due to pipe friction(d) Head loss when the fluid passes through a valve.
