7. For a pipeline, which of the following statements is not correer? a. The energy line represents the variation of the total energy (ie, sum of the elevation head, pressure head, and velocity head) along the pipeline b. The hydraulic gradeline represents the variation of piezometric head (ie, sum of the elevation head and pressure head) along the pipeline. c. The energy line is parallel to the hydraulic gradeline along a pipeline of varying diameter d. None of above e. All of above For a pipeline, which of the following statements is not correct? a. Minor head loss can be calculated by multiplying the velocity head with a loss 8. coefficient. b. Entrance head loss is the energy loss that occurs at the inlet of the pipe. Exit head loss is the energy loss that occurs at the outlet of the pipe. d. c. None of above Which of the following statements is not correct? a. The flow rate between two reservoirs with a constant elevation difference can 9. be increased by installing an additional pipe. b. The flow rate between two reservoirs with a constant elevation difference can be increased by installing a pump c. None of above d. All of above 0. Which of the following statements is not correct? a. Hazen-William coefficient is only a function of pipe material. b. Darcy-Weisbach friction factor does not decrease with increasing diameter of the pipe if pipe material and water temperature remain unchanged. c. None of above d. All of above

Explanation / Answer

The TEL is sum of piezometric line plus kinetic enegry line and HGL is combination of datum head plus pressure head.

So all the statements are true.

Hence option d is correct
