Series and parallel circuits

flight speeds it will slow down. Thus the internal profile of the inlet has to accommodate both accelerating and diffusing flow without undue losses. For supersonic aircraft, the inlet has features such as cones and ramps to produce the most efficient series of shockwaves which form when supersonic flow slows down. The air slows down from the flight speed to subsonic velocity through the shockwaves, then to about half the speed of sound at the compressor through the subsonic part of the inlet.…

In parallel flow heat exchanger working fluids are enter the heat exchanger at the inlet end of the tube side and travel to the opposite outlet end in parallel streams. In a counter flow arrangement, the working fluids are incoming at opposite ends of the heat exchanger and flow in parallel but opposite directions. Temperatures within the two media incline to slant one another in a closely linear…

Chapter 3 Experimental Setup 3.1 Test rig components and description: Fig. 3 illustrates schematic view of the test rig of an IDX-SAHP system. It was designed for a typical UK home administering up to 350 L/day of DHW. The main components are numbered in (Fig.3). The evacuated tube collector installed outdoor on a south facing roof has a surface area of 3.021 m2 with a 52-degree inclination (tilt angle). A 300L, stainless steel, insulated water storage tank has two coils immersed inside, one for…

“One hires the best consultants on airfield layout, noise impacts, terminal layout, on-site roadways, off-site roadways, cost estimating, financial analysis, and forecasting,” observed DIA administrator Gail Edmond. “They brainstorm and generate as many alternate layouts as possible.” Alternatives were discussed and eliminated at periodic joint working sessions, and a technical subcommittee was organized to gather input from the eventual airport users, airlines, pilots, and the FAA. “Everybody…

Unfortunately, some companies have mismanaged their greatest asset—their brands. This is what befell the popular Snapple brand almost as soon as Quaker Oats bought the beverage marketer for $1.7 billion in 1994. Snapple had become a hit through powerful grassroots marketing and distribution through small outlets and convenience stores. Analysts said that because Quaker did not understand the brand’s appeal, it made the mistake of changing the ads and the distribution. Snapple lost so much…
