A bare slab fuel element is 0.2 inches thick with a thermal conductivity of 10 BTU/hr-ft-F. It produces avolumetric heat rate of 5x107 BTU/hr-ft³. At the left hand side (x = 0), the convective heat transfercoefficient is 400 BTU/hr-ft²-F with a fluid temperature of 700 F. At the right hand side (x=0.2inches), theconvective heat transfer coefficient is 300 BTU/hr-ft²-F with a fluid temperature of 700F.a) Determine the steady state temperature distribution in the slab. (Hint: Remember whenapplying heat flux boundary conditions that you must consider the direction of the heat flux)b) At what position is the maximum temperature in the slab and its temperature?--c) What is the temperature at each face?d) What is the surface heat flux at each face?

Please help! Thank u! 3. Consider the following systems. a) What is the heat capacity of a system consisting of a 0.870-kg brass cup filled with 0.0500 kg of water? Specific heats of brass and water at 1.00 atm and 20.0°C are 0.384 kJ/kg•K and 4.186 kJ/kg/K respectively. b) What is the heat capacity of a system consisting of 8.10 kg of water in a 0.310-kg aluminum bucket? Specific heats of aluminum and water at 1.00 atm and 20.0°C are 0.900 kJ/kg-K and 4.186 kJ/kg:K respectively.
QUESTION 3 A dead body was found within a closed room of a house where the temperature was a constant 66 °F. At the time of discovery, the core temperature of the body wasdetermined to be 88 ° F. One hour later a second measurement showed that the core temperature of the body was 77 ° F. Assume that the time of death corresponds to t = 0 and that the core temperature at that time was 98.6 ° F. Determine how many hours elapsed before the body was found. Type your answer in hours in the space provided below. Round your answer to one decimal place.
Q1. Well water contained in an AISI 304 SS pipe network for chemical treatment and posterior distribution by aerial water pipes to different locations in a food manufacturing facility was analysed. The AISI 304 SS pipe network had an approximate 300 m length, 154 mm diameter and 2.0 mm wall thickness. The AISI 304 SS pipes were welded using a Tungsten Inert Gas (TIG) welding procedure. In-situ weld quality assurance was tested by pressurized WW, and no pinhole leakage was detected. After the pipe network remained out of service for 6 months at room temperature containing stagnant, pressurized well water, pitting corrosion was observed on the weld joints and the base material by the presence of multiple pinhole leaks.(a) Discuss, with chemical equations if relevant, TWO corrosion events that may have caused the pitting corrosion.(b) What practical steps could have been taken to mitigate for this potential outcome?(c) Identify corrosion inhibition methods to mitigate for the corrosion…
7. In the summer it tends to become quite hot and humid in the Guelph area. Many home owners purchase dehumidifiers to remove moisture from the air. Excessive moisture can create problems with dampness in basements, so it is a good idea to keep the situation under control, Dehumidifiers work on the principle that when air is cooled, its ability to hold moisture decreases Therefore, the dehumidifier consists of a cabinet-like structure containing a refrigeration coll. As the room air blows over this coil. it is cooled to a temperature that is below its dew point. Moisture then condenses out of the air and is collected in a bucket (or directed by a hose to a floor drain), A curious home owner wonders how much water will be collected in a 12 hour period. He empties the bucket at the start of the test and comes back exactly twelve hours later to see how much water has been collected. Calculate the amount of water that would be collected in a twelve-hour period if 1.15 cubic metres per…

The thermal boundary layer in heat transfer exists whenever there is a difference between the temperatures of the fluid and the outside environment. For fluid flow, how does a boundary layer form?A. Because common surfaces are not smooth, the flow is hindered, and boundary layers are formed.B. The disturbances on the streamlines in high Reynolds number flow produces boundary layer.C. The existence of walls or “boundaries” that keep the fluid inside (or outside) creates the boundary layer.D. Velocity profiles are inherently approaching no-slip condition because of the resistance of the walls.
a. An air stream passing through a 2-inch (1/6 ft) diameter, thin-walled tube is to be heated by high- pressure steam condensing on the outer surface of the tube at 320 °F. The overall heat transfer coefficient, h between steam and air can be assumed to be 25 Btu/(ft2.hr °F) with the air entering at 100 ft/sec, 10 psia, 40 °F. The air is to be heated to 150 °F. Determine the tube length required. Assuming Rayleigh Line flow, calculate the static pressure change due to heat addition. Also, for the same inlet conditions, calculate the pressure drop due to friction, assuming Fanno flow in the duct with f = 0.018. b. c. d. To obtain an approximation to the overall pressure drop in this heat exchanger, add the two results. Discuss the accuracy of this calculation.
My buddy is starting to get hypothermic (body temperature 306 K) during an epic backcountry ski adventure. Since I'm quite warm (body temperature 310 K), I decide to get in a sleeping bag with him to try and warm him up. What heat transfer mechanism will be most responsible for heating him up? For simplicity, ignore any internal temperature differences across my body (that is, assume my skin temperature is also 310 K). Use numbers to support your answer (for human skin, you can use the following values: surface area A = 1:50 m2, emissivity = 0:970, thickness d = 0:0250 m, thermal conductivty 0:200 JmsK)
