5/10 5 View Policies Show Attempt History An experiment is designed to study microscale forced convection. Water at Tm. i - 300 K is to be heated in a straight, circular glass tube with a 60-um inner diameter and a wall thickness of 3 mm. Warm water at Too - 350 K, V - 2 m/s is in cross flow over the exterior tube surface. The experiment is to be designed to cover the operating range 15...

please show work thank you
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....

= 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...

= 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...

= 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...

Consider a rectangular fin (k = 180 W/m-K) of length L =10 mm, thickness i =1 mm, and width w» t. The base temperature of the finis Ty = 150°C, and the finis exposed to a fluid of temperature T, =25°C. Assuming a uniform convection coefficient of h = 110 W/m2.K over the entire fin surface, determine the fin heat transfer rate per unit width 4; efficiency ng: effectiveness es, thermal resistance per unit width and the tip temperature T...

Consider the manufacture of photovoltaic silicon where a thin sheet of silicon is pulled from the pool of molten material very slowly and is subjected to an ambient temperature of T 627°C within the growth chamber. The silicon sheet is Wsi =85 mm wide and tsi =150um thick. A convection coefficient of h 7.5 W/m2.K is associated with the exposed surfaces of the silicon sheet when it is inside the growth chamber. Calculate the maximum allowable velocity of the silicon...

Question 1: Your bear cooler is made of 20-mm-thick polystyrene (k = 0.021 W/m.K) and has interior dimensions of 0.5 mx0.3 m X 0.3 m. If you fill the inside with an ice-water mixture (so the temperature is maintained at 4°C) and leave the cooler on the porch on hot summer day (ambient temperature of 30°C ), what is the heat flux through the container wall? Assume negligible heat gain through the base of the cooler. You may have to...
