° A reservoir supplies water to reservoirs B and C, but in C it is only possible when the valve is open. This action causes a decrease in flow rate in reservoir B, so as an expert in the field, you are asked to calculate the decrease in flow rate in reservoir B after opening the valve. Assume that the diameter and friction coefficient are constant throughout the system, with values of 0.2 m and 0.02 m, respectively. Ignore individual losses. Data: L1 = 80 m; L2 = 40 m; L3 = 75 m 15 m A 3 0m 0m B с válvula
