A horizontal pipe (300 mm dia. And 300m length) leaves a reservoir of surface elevation 60 m at an elevation of 54 m. This pipe connects (abrupt contraction) to a 150 mm diameter pipe of length 300 m running to elevation 30 m, where it enters a reservoir of surface elevation 39 m. Assuming friction factor of 0.02, calculate the flowrate through the line.
