Aim is to transmit water from the source to the end point. Option is to use gravity pipeline system (may use tools i.e. pump, air valve, pressure reducer, etc if required!). Problem The following system transmits water from Reservoir A to Reservoir B by means of a gravity pipeline where, L-3500m, f=0.017 and D=0.7m for all pipes. This pipe line has two high points at C and E, where small-orifice air valves are installed. Assume that the valves require 5m of line pressure head for proper operation. Checking the design specifications [(0.5m/s <u<2.0m/s) and (5m<P/y<80m)] at required locations. a) determine the maximum discharge that the system can supply, and b) determine the head loss at the exit valve such that no open channel flow is to be developed. 280m 290 Reservoir A 250m 240m 230m 230m Valve 230m 225m G Free jet Reservoir B Aim is to transmit water from the source to the end point.
