1. A 0.2-m-diameter cast-iron pipe and a 67-mmdiameter commercial steel pipe are parallel, and both run from the same pump to a reservoir. The pressure drop is 210 kPa and the lines are 150 m long. Determine the flow rate of water in each line.

2. A system consists of three pipes in parallel with a total head loss of 24 m. Data for the three pipes are as follows:

For water at 20C, neglect minor losses and determine the volumetric flow rate in the system.
