Water at 27℃ flows from a storage tank through 170 m of a steel pipe with an internal diameter of 154 mm. Taking the energy loss due to friction into account, calculate the required head h above the pipe inlet to produce a volume flow rate of 70.8 L/s.
Simple application of Bernauli theorem considering friction losses. for calculating friction factor I have used Swamie and Jain formula, one can use some other formula also. process will be the same. pressure at the top is not given so I took it to be atmospheric pressure. And dia of the tank is also not given so we can take to be large.
