View Policies Show Attempt History An aluminum transmission line with a diameter of 20 mm has an electrical resistance of Relec' = 2.636 x 109/m and carries a current of 700 A. The line is subjected to frequent and severe cross winds, increasing the probability of contact between adjacent lines, thereby causing sparks and creating a potential fire hazard for nearby vegetation. The remedy is to insulate the line, but with the adverse effect of increasing the conductor operating temperature....

= To cool a summer home without using a vapor-compression refrigeration cycle, air is routed through a plastic pipe (k = 0.15 W/m-K, Di -0.15 m, Do-0.17 m) with a smooth interior surface that is submerged in an adjoining body of water. The water temperature is nominally at Too = 17°C, and a convection coefficient of ho- 1500 W/m2K is maintained at the outer surface of the pipe. Air from the home enters the pipe at a...

= The use of rock pile thermal energy storage systems has been considered for solar energy and industrial process heat applications. A particular system involves a cylindrical container, 2 m long by 1 m in diameter, in which nearly spherical rocks of 0.03-m diameter are packed. The bed has a void space of 0.42, and the density and specific heat of the rock are p = 2300 kg/m and cp = 879 J/kg-K, respectively. Consider conditions for...

An air-cooled steam condenser is operated with air in cross flow over a square, in-line array of 400 tubes (NL=NT-20), with an outside tube diameter of 20 mm and longitudinal and transverse pitches of SL-60 mm and ST = 63 mm, respectively. Saturated steam at a pressure of 2.455 bars enters the tubes, and a uniform tube outer surface temperature of Ts=390 K may be assumed to be maintained as condensation occurs within the tubes....

= View Policies Show Attempt History A novel heat exchanger concept consists of a large number of extruded polypropylene sheets (k = 0.17 W/m-K), each having a fin- like geometry, that are subsequently stacked and melted together to form the heat exchanger core. Besides being inexpensive, the heat exchanger can be easily recycled at the end of its life. Carbon dioxide at a mean temperature of 10°C and pressure of 2 atm flows in the cool channels at a mean...

To maximize production and minimize pumping costs, crude oil is heated to reduce its viscosity during transportation from a production field. (1) Consider a pipe-in-pipe configuration consisting of concentric steel tubes with an intervening insulating material. The inner tube is used to transport warm crude oil through cold ocean water. The inner steel pipe ks 45 W/m-K) has an inside diameter of Di,1 150 mm and wall thickness t = 20 mm while the outer steel pipe has an inside...

Heat is uniformly generated at the rate of 4 x 105 W/m3 in a wall of thermal conductivity 25 W/m-K and thickness 60 mm. The wall is exposed to convection on both sides, with different heat transfer coefficients and temperatures as shown. There are straight rectangular fins on the right-hand side of the wall, with dimensions as shown (Lf = 16.25 mm) and thermal...

Hot exhaust gases are used in a shell-and-tube exchanger (1 shell and 20 tube passes) to heat 2.5 kg/s of water from 35 to 84°C. The gases, assumed to have the properties of air, enter at 200°C and leave at 93°C. The overall heat transfer coefficient is 181 W/m²K. Using the effectiveness-NTU method, calculate the area of the heat exchanger....
