GATE Civil Engineering (CE) 2015 Shift 1 Solved Paper

Two reservoirs are connected through a 930 m long, 0.3 m diameter pipe, which has a gate valve. The pipe entrance is sharp (loss coefficient = 0.5) and the valve is half-open (loss coefficient = 5.5). The head difference between the two reservoirs is 20 m. Assume the friction factor for the pipe as 0.03 and g =10 m/s². The discharge in the pipe accounting for all minor and major losses is _______________ m³/s.
