Design a thermoelectric refrigerator that is capable of cooling a canned drink in a car. The refrigerator is to be powered by the cigarette lighter of the car. Draw a sketch of your design. Semiconductor components for building thermoelectric power generators or refrigerators are available from several manufacturers. Using data from one of these manufacturers, determine how many of these components you need in your design, and estimate the coefficient of performance of your system. A critical problem in the design of thermoelectric refrigerators is the effective rejection of waste heat. Discuss how you can enhance the rate of heat rejection without using any devices with moving parts such as a fan.
Evaporation from a nearby lake was 8 in. during June. It is estimated that 25 percent more will evaporate from the pool than the lake. On July 1, the pool is 5 inches below the top. Does the pool have a leak? If so, what is the rate of leakage in gal..
A cylindrical specimen of soil is compressed by an axial principal stress of 500 kPa and a radial principal stress of 200 kPa. Plot Mohr's circle of stress and determine (a) the maximum shear stress
A 200 foot long, 2.5 feet in diameter, straight, corrugated metal storm drain pipe, is used to drain a parking lot. The elevation difference between the pipe ends is 8 feet. What velocity would be expected
The only work interaction between the system and the surroundings is via the paddle wheel. The work done on the system via the paddle wheel is 220 ft*Ibf and the heat interaction can be assumed negligible.
A chemical mixing basin is to be designed to blend chlorine and treated wastewater. The basin flow is 700 gallons per minute and the basin dimensions are 5 feet by 5 feet by 5 feet water depth.
The following boundary conditions apply at x=0, ca = Keqcao and T=To and at x=L, (dco/dx)=0 and (dT/dx)=0. Determine the concentration and temperature profiles for this system.
A first order reaction occurs in a PFR at the rate of 2.1 hr^-1. The reactor volume is 1400L and flow is 15 gpm. If the influent concentration is 200 mg/L, then what is the effluent concentration?
during the next month, the amount of water available for a city is lognormally distributed with a mean of 1 million gallons and a c.o.v. of 40%, where as the total demand is expected to follow a lognormal distribution
Place the scientific mass on the inclined plane and string over the pulley. Using a force-measuring device, pull the string and determine the force needed to obtain static equilibrium.
For Vectors A=(i + 2j - 3k) and B=(4i - 5j + 6k), determine:
A 230,000-lb space shuttle orbiter touches down at about 220 miles per hour (mph). At 200 mph, its drag parachute is deploys. The wheel brakes are applied at 100 mph until wheel sotp and the drag parachute is jettisoned from the orbiter at 35 mph.
A 1.0-m rigid horizontal support is hung by two cables as shown. One cable is brass and The other cable is high-density polyethylene plastic. At room temperature (21°C), the cables measure 3.50 m vertically. When the temperature drops to 15°C, find t..
