Four buildings, shown in Fig. P1-30 as A, B, C, and D are to be cooled using a central chilled water facility, shown as Supply. The figure is considered to be close enough to a scale drawing to be used for preliminary layout purposes. Ethylene glycol, a commonly employed heat transfer liquid medium, is to […]

Pipe velocities much in excess of 10 ftls should be avoided. Limit the number of sizes (ANSI schedule 40) to 4 (buildings A and B, building C, building D, and the supply/return loop to the chiller and main pump). Provide valves to isolate each pump. (Note that items 1 and 2 may do the job.)

As shown in Fig. P1-32,an underground salt dome is used to store gasoline (octane). Access to the salt dome is provided using an annular pipe arrangement. The outer pipe is schedule 160, 24-in. nominal; the inner pipe is schedule 80, 12-in. nominal. When salt water is pumped into the pipe, the octane is forced upward

Auric Enterprises, Inc., is converting a five-story office building into an engineering office complex.A sketch of the building is given in Fig. P1-31. The company must add a new cooling system to the building. The chiller is to be placed in the mechanical room located on the first floor. Chilled fluid is to be pumped

A 250-ft-high office building has a 6-in. diameter steel standpipe and a 100-ft long 2-&-in. diameter fire hose on each floor. The nearest fireplug is 100 ft away from the standpipe’s ground connection. The firefighters connect a 6-in. diameter, 50-ft long hose from the fireplug to the pump on the fire truck and a 4-in.

Figure P1-33 illustrates a pumped-hydroelectric storage system. During a 12-hr period at night when the demand for electricity is low, electrical motor-driven pumps transfer water from the lower reservoir to the higher reservoir. During the 12-hr period in the daytime when the electrical demand is high, water from the upper reservoir is discharged through turbines

Since the early 19OOs,the Grand Canyon has become a popular attraction for tourists. The lack of potable water is a major hindrance to visitors, however, as permanent natural sources of water are rare or nonexistent on the canyon rim. The Utah Parks Company plans to construct a 12,500-ft pipeline of schedule 80 commercial steel pipe

A cooling system has been constructed for the English Channel Tunnel or “Chunnel,” which runs 130 ft below the seabed, linking Great Britain and France. The Chunnel consists of three tunnels, each 31 miles long. Passengers and cargo trains travel in the two main tunnels (7.6 m in diameter) at speeds up to 100 mph.
