Question

Two reservoirs are connected through a 930 m930\text{ m} long, 0.3 m0.3\text{ m} diameter pipe, which has a gate valve. The pipe entrance is sharp (loss coefficient =0.5= 0.5) and the valve is half-open (loss coefficient =5.5= 5.5). The head difference between the two reservoirs is 20 m20\text{ m}. Assume the friction factor for the pipe as 0.030.03 and g=10 m/s2g = 10\text{ m/s}^2. The discharge in the pipe accounting for all minor and major losses is ________________ m3/s\text{m}^3/\text{s}.
