Question : Studies show that the major energy consumption in Fijian villages is wood which is used for cooking over open fires. Typical consumption of wood is 1 kg person–1day–1. (a) Estimate the heat energy required to boil a 2-liter pot full of water. Assuming this to be the cooking requirement of each person, compare this with the heat content of the wood, and thus estimate the thermal efficiency of the open fire. (b) How much timber has to be felled each year to cook for a village of 200 people?Assuming systematic replanting, what area of crop must the village therefore set aside for fuel use if it is not to make a net deforestation? Hint: refer to Table 10.4. (c) Comment on the realism of the assumptions made, and revise your estimates accordingly. Answer: (a) mcDT ≈ 0.6 MJ (heat losses from pot imply actual requirement is higher). h ≈ 3%. (b) 70 tonnes; 7 ha.

Read the question carefully and give me all a, b & c solutions. Note: kindly answer all otherwise leave it. A circular nylon [E = 8 GPa; ν = 0.35; α = 22 ×10-6/°C] disk with a circular hole in its center is shown. At an initial temperature of Ti = 15°C, the outer diameter of the disk is D = 200 mm, the diameter of the central hole is d = 55 mm, and the thickness of the disk is t = 22 mm. At a final temperature of Tf = 51°C, determine:(a) the change in diameter Δd of the central hole (assume an increase Δd as positive, otherwise as negative).(b) the change in thickness Δt of the disk (assume an increase Δt as positive, otherwise as negative).(c) the normal strain in the circumferential direction around the outside of the disk
The Diamond Ring Solution. The processing chip on the computer that controls the navigation equipment on your spacecraft is overheating. Unless you fix the problem, the chip will be damaged and the navigation system will shut down. You open the panel and find that the small copper disk that was supposed to bridge the gap between the smooth top of the chip and the cooling plate is missing, leaving a 2.0 mm gap between them. In this configuration, the heat cannot escape the chip at the required rate. You notice by the thin smudge of thermal grease (a highly thermally conductive material used to promote good thermal contact between surfaces) that the missing copper disk was 2.0 mm thick and had a díameter of 1.2 cm. You know that the chip is designed to run below 65 °C, and the copper cooling plate is held at a constant 5.0 °C. (a) What was the rate of heat flow from the chip to the copper plate when the original copper disk was in place and the chip was at its maximum operating…

The manufacturing process for making a 55 cm X 70 cm antiviral silver coated plastic sheet used to make a face shield involves heating the material at 400 ̊C followed by a special treatment at 360 ̊C for 20 mins. When a uniform temperature of 360 ̊C is reached within the material, the silver coated sheet is immersed into a solution at 30 ̊C. The thickness of this silver coated sheet is 9 mm.(a) What is the time at which the temperature of the sheet becomes 125 ̊C ?
