An irrigation system is arranged as shown in the figure, with water from two pipes (DA=DB=1in) flowing onto the ground. When A nozzle meter (d= 0.5in ) on pipe A is connected to a manometer that uses a fluid with a density of 6000kg/m3, the difference in fluid heights within the manometer is 20cm. Minor losses can be neglected. Taking friction factor in both pipes to be f=0.02, find the flowrate
