2.30 An electrical heater capable of generating 10,000 W is to be designed. The heating element is to be a stainless steel wire having an electrical resistivity of ohm-centimeter. The operating temperature of the stainless steel is to be no more than 1260°C. The heat transfer coefficient at the outer surface is expected to be no less than in a medium whose maximum temperature is 93°C. A transformer capable of delivering current at 9 and 12 V is available. Determine a suitable size for the wire, the current required, and discuss what effect a reduction in the heat transfer coefficient would have. (Hint: Demonstrate first that the temperature drop between the center and the surface of the wire is independent of the wire diameter, and determine its value.)

In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .
In a company there are the following consumptions for energy and energetics. The company works 8hours a day and consumes an average of 10 kWh/day of electrical energy, its thermal energy production system(heating) works through the combustion of a gas that provides 111.76 kcal/h for each gram that isgas flaring, using an average of 0.25 lbm/h of gas.Fuel is also used in another thermal system that on average consumes 1 lbm/h, whose density is 1.1g/mL with calorific value of 1193.45 BTU/lbm. If the average costs for energy and energy are of$0.20/kcal. Determine the total cost of energy and energy for each work week (6 days per week).week)
During summer season a room measuring 10 x 13 x 6 m3 is cooled electrically from initial temperature- 28°C to 2°C. The air pressure inside the room is the same as that of surroundings and is equal to 72 cm of Hg. The pressure remains constant during the cooling process. The cooling capacity of furniture and wall is 35 kJ/K. The Cp of air is 1.005 kJ/kgK.Calculate the amount of electric energy needed for cooling the room. How much air comes through gaps and windows during cooling period?
