2.3 (a) Size the pipes of the following hydraulic network. Assume an average speed in pipes not to exceed 4 ft/s. The lengths of the straight pipes between the point A and B are 600, 130 and 120 ft for fluid passing through chiller, coils 1 and coil 2, respectively. Assume the head loss in chiller coils 1 and coil 2 are 50, 20 and 35 ft of water, respectively. (b) Determine the maximum head loss occurring in the circuit and identify in what path it Occurs. (c) Select the suitable size of the pump and its speed that consumes the least power to maintain the flow. If required, you may select two pumps to operate in parallel/or series mode to meet the requirement. You may use the pump characteristic of the handout on pumps and ping systems operating at 3500 rpm. 600, 250 gpm chiller Globe valve (GV) B Coil 1 Coil 2 130°, 100 gpm Globe Valve 120, 150 gpm Gate Valve pump A Gate Valve sid elbow, threaded (typ.)
