Question
A 160 mm pipe branches into a 100 mm pipe and a 50 mm pipe, as shown in the figure. In both pipes, as indicated, they are made of hydraulic copper 30 m long, the fluid that circulates is water at 10°C.
Determine what the resistance coefficient K of the valve should be to obtain equal flow rates of 400 L*7min in each branch
