A pipe is replaced by two pipes in parallel that have half the diameter of the original pipe. What is the ratio of the volume flow rate through both of the two smaller parallel pipes to the flow through the single, larger pipe? The lengths of the pipe, the fluid properties, the pressure drop, and the value of the friction factor are identical in both situations. The length of the pipes is much larger than the separation between the two smaller, parallel pipes. Give your answer to two decimal places.
Water at 20°C is to be pumped from a reservoir (Z₁ = 5 m) to another reservoir at a higher elevation (zB = 13 m) through two 36-m-long pipes connected in parallel, as shown in Fig. 1.
