Provide answers for the following: a) What is Cavitation generally? b) What is the effect of Cavitation in Pumps? c) Imagine that you are working as a Pump Operator in the City's water storage and distribution system. You are dealing with various pump machineries and in-charge for the installation, maintenance, repair and Servicing. In your day-to-day work, you are facing various pump cavitation issues due to change in water availability and distribution demand Brief the nature of every issue listed below and recommend a suitable solution to avoid cavitation. i. Cavitation occurring when reducing Suction head. ii. Cavitation that occurs when the distribution system is re-constructed with pump mounted away from the source tank by double the distance. iii. Cavitation that occurs when the velocity of the fluid in the suction piping is increased to 12 ft per second. iv. Cavitation that occurs when the Net positive suction head Required (NPSHr) is increased by 1.5 times due to huge demand in the water distribution system
