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...

) 25 points - Water flows in a piping system a section of which is shown below.Pipe is 30 mm ID commercial steel pipe. Velocity of flow is 1.6 m/s and is constant throughout. Pressure at Pt is 200 kPa. All the valves are fully open gate valves, all the elbows are regular 90° threaded. For water, p:1000 kg/m3, 0.00108 N-s/m2. Other necessary data is given on the diagram. Assume the flow is incompressible and steady. Determine the volume flow...
Water with a velocity of 5m/s flows through the parallel concert piping system with a relative roughness of 0.04 shown below. The entrance diameter is 4m, the length of the parallel pipes is 40 m and L/d for the pipes at A and B is 10m. Here the pressure at the inlet of the system is measured by a mercury manometer directly below it. Given your understanding of the flow of incompressible fluids,notice the squared inlet edge and four standard...

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.

Consider water flowing to three faucets in a building through the very simple plumbing network shown below. Every section of pipe in the figure is 25 ft long. Ali of the piping is nominal half-inch type L copper piping. The inlet pressure to the main pipe is constant at 50 psi and the pressure of the water leaving each faucet is 0 psi. The water has a temperature of 140°F. For the purposes of this analysis assume that there are...
Water (p=998kg/m^3,
u=0.001Pa*s) flows from reservoir A to reservoir B through the
piping system shown. Each elbow has a minor loss coefficient of
1.2. Each valve has a minor loss coefficient of 3.2. The entrance
and exit are both sharp edged. Determine the flow rate L/min. You
now need to modify the piping system to increase the flow rate to
100L/min by reducing the length of the 25mm pipe. What must new
length of the 25mm pipe be?
