Vacuum furnaces are used in manufacturing for metal heating in brazing and sintering processes, as well as for heat treatment of steel alloys. The vacuum, and absence of air/oxygen, facilitates a low contamination process and prevents detrimental surface oxidisation. Heat is often provided in these furnaces by electrical heating elements, and their thermal design is critical to the effective operation of the furnace. In one such case, this element is modelled as a long, cylindrical electrically heated rod, 20 mm in diameter installed in a vacuum furnace as shown. The surface of the heating rod has an emissivity of 0.9 and is maintained at 1000 K, while the interior walls of the furnace are black and are at 800 K. Calculate the net rate at which heat is lost from the rod per unit length.
9.3 A 5 cm? thin film solar cell has a reverse saturation or dark current 1, = 5.9 x 10-15 mA. Under the insolation Ia of 900 W/m?, the short-circuit current Ie is 124 mA. At the cell temperature of 25°C, V,= kT/q = 0.026 V. Determine: (i) open-circuit voltage Voc, (ii) MPP voltage Vm and current Im, (iii) maximum power output Pm, (iv) fill factor FF of cell I–V characteris- tics, and (v) cell efficiency n..
Quiescent means that you will be using natural convection (so buoyancy type of convection) (not forced convection)
Required information A masonry cavity wall consists of 100-mm common bricks, 90-mm air space, 100-mm concrete blocks made of lightweight aggregate, 20-mm air space, and 13-mm gypsum wallboard separated from the concrete block by 20-mm-thick (1 in x 3 in nominal) vertical furring whose center-to-center distance is 400 mm. One side of both air spaces is coated with a reflective film of = 0.05. The temperature difference across the air spaces can be taken to be 16.7°C with a mean air temperature of 10°C. The air space constitutes 81 percent of the heat transmission area, while the vertical furring and similar structures constitute 19 percent. The R-values for different materials are given in the table below. Construction 1. Outside surface, 24 km/h 2. Face brick, 100 mm 3. Air space, 90-mm, reflective with & = 0.05 4.

Can someone please help me to solve all of the following question showing all work and explanation as well as graphs needed in excel with formulas. Thank you!
Show the thermal circuit by labeling all the thermal resistances. Calculate and tabulate the thermal resistances (assume Tavg=470 K for the air gaps). If q''rad= 0.25W/cm^2, what is the outer surface temperature of turnout coat for inner temperature of 66C.
Question One Explain how heat is transferred from one point to another illustrating with appropriate diagram. Calculate the heat flow per square meter (heat flux) through water medium with thermal conductivity of 0.6, flowing in a 5 cm thickness space, if the temperatures on the two surfaces are 50 and 210°C, respectively. Question 2 Distinguish between force and free convection with the aid of appropriate illustrations. What is the approximate temperature difference between a hot plate and the surrounding air if the heat flux from the plate is 800 W/m2? Assume that the air is flowing past the surface with a velocity of 5 m/s giving a heat transfer coefficient of 20 W/(m2K). Question 3 Explain the differences between laminar and turbulent flow Water (ν = 0.86x10-6m2/s) flows through a tube with the diameter 12 mm at a velocity of 2 m/s. Determine if the flow is laminar or turbulent!
To reduce heat flux, the skin is wrapped with a clothing material. What should be the thickness of the clothing material covering the surface of this skin tissue to reduce the heat flux to half of its original value? What is the temperature at the skin-clothing material interface? Note: if you think you need to have more information to solve this problem, you're free to make assumptions. Please state them clearly in your answer, if you need to make such assumptions.

2. A heater is a thin vertical panel 1.0m long and 0.7m high and is used in a warehouse to keep workers warm. The heater has air circulating on each side. Assume the maximum temperature of the panel is 60°C (already above the board line that is safe for human hands to touch briefly without getting hurt). Assume the room air temperature is 18°C but the warehouse wall temperature is 5°C. Model the surface with an emittance of 0.9 and Vair = 1.57x105 m²/s. a. Determine the maximum power rating for the heater. b. Now if you run the heat by standing on its side (it will be 1.0 m high and 0.7 m long), determine the surface temperature. c. Compare case a and b and explain any differences you see.
Question: a) We want to increase heat transfer by placing fans to provide forced convection to reduce the length of the pipe necessary (Note that the outside surface temperature of the pipe remains the same at 100oC). What is the rate of heat transfer from pipe to the air per meter length if the air speed over the pipe surface is 5m/s? What is the total length of the pipe necessary? Problem: Consider a rectangular warehouse with the dimensions of 40m long x 20m widex10m height. The overall heat transfer coefficient for all sidewalls is Uwall=0.3 W/m2K (Approx. R=20 hr.ft2.oF/Btu) and for the flat roof, it is Uroof= 0.20W/m2K. The floor can be assumed to be insulated and we can ignore the heat transfer through the doors, etc. We want to maintain the inside air temperature at 15oC while the outside temperature is 0oC by using a thin-walled, 5.0cm diameter copper pipe that carries steam. Steam enters the pipe as saturated vapor at 100oC. So, as it starts losing heat to the inside air, it…
