Does watercad perform hydraulic analysis of the distance covered with pipes from the ground to the base elevation level of an elevated tank raised from the ground level?If not how can I factor the loses into my model?
The pipe connecting to the base elevation of the tank in a network is not explicitly modeled in WaterCAD. However, you can add minor losses to the pipes for bends, valves etc. under the "Specify Minor Losses" field found in the pipe properties. Here is an article which describes in detail how multiple minor losses can be added to a pipe.
Adding Multiple Minor Losses To a Pipe
This way you can simulate the hydraulics and the resulting losses for your pipe connecting the elevated tank.
Hope this helps.

Thank you for your reply above but unfortunately, I don't think your suggestion will solve my problem.It's very true that I can add minor losses to pipes and bends.In the scenario above, the pipe that I am talking about isn't in existence; it is virtual but in a real or actual scenario it has to be there in order to feed water into the elevated tank.Assuming my tank is a 12m elevated tank, how will I hydraulically analyze the flow through this pipe and factor in all the losses as the water drains into the tank?
If you need to account for losses in this pipe, you may want to consider applying some additional headloss to an existing pipe, as Yashodhan mentioned, or modeling the pipe explicitly.
However, you may want to do a sensitivity analysis on this as well. For instance, if the pipe is relatively short and relatively large in diameter, the losses may not be significant enough to worry about the losses involved.
Thank you for your comments.Though, An additional hydraulic analysis will make it better.Even if it is introduced into the software and then calculated virtually and later on added to the final pipe results.The concept will save us the users some time since smaller sized pipes (32mm,40mm and 63mm) tend to have a great amount of frictional losses.If we are talking of 9 to 12 m length of pipes then that can cause a big effect.As it is now, let me go by your suggestion
