For the parallel-pipe system shown in the figure, each pipe is cast iron, and the pressure drop p1 - P2 = 3 Ibf/lin?. The lengths of the pipe are La = 260 ft and Lb = 310 ft. If the two pipes are in series, what will the flow rate be? The fluid is SAE 10 oil at 20 °C. For SAE 10 oil at 20 °C, take p = 1.69 slug/ft³ and µ = 0.00217 slug/ft-s. Round the answer to four decimal places. D = 3 in Lb D= 2 in La

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condit…
