Example of Pipe Sizing The figure shows a closed piping system to supply chilled water to two heat exchangers. Size the pipe for this system, assuming schedule-40 steel pipe is used with threaded (screwed) fitting. Determine the pump flow rate and head requirements. Distances are as shown in feet. Head losses through the heat exchangers and chiller are shown as provided by the manufacturers. Q(gpm) Head Loss (ft) 70 Unit Chiller Heat Exchanger (a) 30 Heat Exchanger (b) 40 12...

The following figure depicts a pipe system connecting two reservoirs. No minor losses should be considered in this problem. Assume that y=62.4 lb/ft. The water surface elevation at Reservoir A is 24 feet, and at Reservoir Dthe water surface elevation is 100 feet. The pump supplies a head of He=100 feet. The pipe system consists of pipes in series with the following characteristics: Pipe ABBCCD Diameter (in) 18 18 Length (ft) 4,000 1,000 2,000 Darcyf 0.015 0.020 0.015 la) Calculate...

The piping system shown in the Figure (which does not show
details of all the fittings) is used to connect a large reservoir
to a pump where it is then pumped to a small wilderness hostel. The
pipe is 2-in. I.D. cast iron and must deliver 80 gal/min of 60°F
water. The 300 ft long pipeline contains four swing check valves
and five 90° standard elbows. All connections are threaded. Find
the head loss between points 1 and 2.
