Repeat Problem 8.117 if the friction factors are not known, but the pipes are steel pipes.

Problem 8.117

With the valve closed, water flows from \(\operatorname{tank} A\) to \(\operatorname{tank} B\) as shown in Fig. P8.117. What is the flowrate into \(\operatorname{tank} B\) when the valve is opened to allow water to flow into tank \(C\) also? Neglect all minor losses and assume that the friction factor is 0.02 for all pipes.
