The figure below shows a condenser/cooling tower pipe system needed to remove heat from a water cooled refrigeration condenser and reject the heat to the atmosphere. The amount of heat to be rejected to the atmosphere is 480,000 Btu/hr. The water enters the condenser at 85"F, and the temperature rise of the water through the condenser is 10°F. The total length of the piping in the system is 60 ft. Fittings are as shown. Assume bends to be as shown...

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 Figure below (Figure 3) shows a pipe system with a valve and two reservoirs
QUESTION3 The Figure below (Figure 3) shows a pipe system with a valve and two reservoirs. A pump transports a constant flow rate of Q = 0.1 m3/s of water from reservoir A to reservoir B. At four sections the pipe has bends and the roughness of the pipe is ks = 1.5 mm. The pipe has a diameter D = 34 cm and a total length L = 500 m. The water level in reservoir B is Δh=4.67 m above...

Water flow in a pipe and then exit through a bended nozzle as shown in Figure 3. The nozzle is connected to the main pipe using a flanged joint at (1). The diameter of the pipe is D1 10 cm and is constant, whilst the diameter at the outlet section of the nozzle (2) is D2 3 em. The flowrate of the water is Q = 15 liter/s and the water pressure at the flange is Pi 230 kPa. By...

A 38-in pump is installed for the system below. The pipe (100-cm diameter) has a friction factor of 0.012 and a total length of 20 km. Given that Ke = 0.5 (pipe entrance) and Kε = 1.0 (pipe exit). For water at 80 degrees Fahrenheit, estimate the flow rate (in gpm), the power required in horsepower, HP), and the net positive suction head required (in ft) to avoid cavitation for the system when the pump running. Elevation = 180 m...

EDIT: The fluid in the system is water. There is no data
regarding the inclination of the pipe. It's known that the
equipment used includes a fluid flow piping system (AFT), hydraulic
bench (FME00), barometer, and psychrometer. Also added an appendix
that has recommended equations.
