A thin brass pipe, 3 cm in outside diameter, carries hot water at 85°C. It is proposed to place 0.8 mm thick straight circular fins on the pipe to cool it. The fins are 8 cm in diameter and are spaced 2 cm apart. It is determined that h will equal 20 W/m².°C on the pipe and 15 W/m².°C on the fins, when they have been added. If T = 22°C, compute the heat loss per meter of pipe before and after the fins are added.

A 4-inch insulated arctic pipe is used for a construction camp. The lake source is 1500 meters away. The line is above ground on mud sills. Calculate the heat loss from the pipe if the outside ambient temperature is -40 deg F (minus 40). and the water coming out of the lake is at 1 deg C. Assume that the ID is 4-inches, OD is 4.5- inches and it s covered by 2-inches of urethane insulation. Use a k-factor of 34.9 BTU/hr-ft-degF for the pipe, 0.16 BTU-in/hr-ft2-degF for insulation, and an inside and outside convective film coefficients of 12.3 BTU/hr- ft2-deg F and 6.2 BTU/hr-ft2-deg F.

Sipho’s mother is making a fire in the stove inside a shack using coal. A fan is used to extract the flue gasfrom the fire via a chimney made of zinc material. The wall thickness of Chimney is L=4mm and the walltemperature of the chimney on the flue gas side is T_si=60˚C. Sipho, playing outside next to the chimneyexperiences an ambient temperature of 20˚C. The surrounding temperature is T_sur=35˚C and the emissivityis ε=0.95. Assume the convection coefficient is 20W/m2K and the chimney is grey material.Under these conditions determine the outer surface (air side) temperature T_so=? of the chimney.

You are designing an enclosure which houses a PCB. Mounted outside the enclosure on its top is a set of aluminum fins, as seen in the sketch below. The enclosure (and fins) are 150mm deep long. There is no forced airflow. Neglect the thickness of the enclosure walls. Neglect heat transfer out of the sides and bottom of the enclosure. If the PCB produces 4000 W/m2: a) Most industrial-grade ICs have a maximum temperature of 85oC. If you must keep your PCB below this what is the maximum thermal resistance from the PCB to the air surrounding the fins? Assume the air around the fins stays at room temperature. b) If the top of the enclosure (and bottom of the fin base) runs at 50°?, what is the effective thermal conductivity above the PCB? Hint: Because the air inside the enclosure is trapped and heats up, any air properties NOT given below are calculated at the average air temperature (T1+T2)/2. c) What is the temperature at the base of the fins? d) What is the efficiency of the fins? e)…
