two pipes each 300 m long are available for connecting to a reservoir from which a flow of 0.085 m3 /s is required.

two pipes each 300 m long are available for connecting to a reservoir from which a flow of 0.085 m3 /s is required. if diameters of the two pipes are 300 mm and 150 mm respectively, determine the ratio of head lost when the pipes are connected in series to the head lost when connected in parallel. neglect minor losses
