Hi everybody,
My query is regarding "the effect of flow rate due to sudden expansion in a pipeline keeping the inlet and out let conditions constant i.e. no pump or turbine in the pipeline"
There is a 50NB (mm, Nominal Bore) tapping in a 150 NB water pipeline and this 50 NB pipeline extend upto the underground tank which is approx. 100 mtrs from the tapping. i.e. the lengh of 50 NB pipe is 100 mtrs. With is arrangement, we are getting, say Q1 flow in the underground tank and the tank is getting 50% filled. Now we want to increase the flow. Hence, we want to do the following modification in the line 50 NB pipeline. We are planning to provide a expander (50 NB x 80 NB) at a distance of approx. 200 mm from the header tapping and will extend the 80 NB upto the underground tank. The entry point of pipe in the underground tank is at the top.
Now, my question is, by doing this modification, whether there is any increase in flow of water so that the u/g tank will get filled with more water?
(Please note that the pressure in the main header (150 NB) is constant and at the end of 80 NB line is also atmospheric pressure.)
I have attached a schematic diagram of the proposed modification for ready reference
Regards,
Shri
