A water supply system draws water from a borewell in the aquifer and transports it to the clear water tank at the water distribution plant. The static head in the calculation of the lift of the water pump for tube wells is ( ). a. The elevation difference between the lowest operating water level of the shaft well and the highest water level of the clear water tank. b. The elevation difference between the designed operating water level of the shaft well and the lowest water level of the clear water tank. c. The elevation difference between the designed operating water level inside the shaft well and the highest water level of the clear water tank. d. The elevation difference between the designed operating water level outside the shaft well and the highest water level of the clear water tank. Answer: c
