Which of the following methods of analysis of water distribution system is most suitable for long and narrow pipe system? A. Circle method B. Equivalent pipe method C. Hardy cross method D. Electrical analysis method

The correct answer is: C. Hardy cross method

The Hardy Cross method is a hydraulic analysis method that is used to determine the flow rates and pressures in a water distribution system. It is a iterative method that solves for the unknown head losses in a system of pipes. The method is most suitable for long and narrow pipe systems, as it is able to accurately account for the effects of friction and other losses.

The other methods listed are not as suitable for long and narrow pipe systems. The circle method is a simple method that is used to estimate the flow rate in a pipe. It is not accurate for long and narrow pipes, as it does not account for the effects of friction and other losses. The equivalent pipe method is a method that is used to combine multiple pipes into a single equivalent pipe. It is not suitable for long and narrow pipes, as it does not account for the effects of friction and other losses. The electrical analysis method is a method that is used to analyze water distribution systems using electrical analogy. It is not as accurate as the Hardy Cross method, and it is not suitable for long and narrow pipes.

Here is a more detailed explanation of each method:

• Circle method
  The circle method is a simple method that is used to estimate the flow rate in a pipe. It is based on the assumption that the head loss in a pipe is proportional to the square of the flow rate. The method is not accurate for long and narrow pipes, as it does not account for the effects of friction and other losses.

• Equivalent pipe method
  The equivalent pipe method is a method that is used to combine multiple pipes into a single equivalent pipe. The equivalent pipe is chosen so that it has the same head loss as the original pipes. The method is not suitable for long and narrow pipes, as it does not account for the effects of friction and other losses.

• Electrical analysis method
  The electrical analysis method is a method that is used to analyze water distribution systems using electrical analogy. In electrical analogy, the pipes in a water distribution system are represented by resistors, and the pumps in the system are represented by voltage sources. The method is not as accurate as the Hardy Cross method, and it is not suitable for long and narrow pipes.
