Why do we need to be careful about work done on the system versus work done by the system in calculations?
An incandescent lightbulb is an inexpensive but highly inefficient device that converts electrical energy into light. It converts about 10 percent of the electrical energy it consumes into light while converting the remaining 90 percent into heat. The glass bulb of the lamp heats up very quickly as a result of absorbing all that heat and dissipating it to the surroundings by convection and radiation. Consider an 8-cm-diameter 60-W lightbulb in a room at 25°C. The emissivity of the glass is 0.9. Assuming that 10 percent of the energy passes through the glass bulb as light with negligible absorption and the rest of the energy is absorbed and dissipated by the bulb itself by natural convection and radiation, determine the equilibrium temperature of the glass bulb. Assume the interior surfaces of the room to be at room temperature.
(1) An incandescent light bulb produces 5.85 Joules of light energy each second. This bulb is 7.80% efficient, meaning that only 7.80% the total energy it consumes becomes light and the rest becomes waste heat. A 12.0 W fluorescent bulb is designed to produce the same illumination (in Joules of light energy per second) as the incandescent bulb. A large building uses 17,530 light bulbs. At a cost of 8.56€/kW-hr for electricity, how much money will the owners of the building save each year if they use fluorescent bulbs instead of incandescent bulbs? Express your answer in dollars. [answer: about $828,000]
A 75 W incandescent bulb and a 15 W compact fluorescent bulb, as shown, each produce 3.0 W of visible-light energy. What are the efficiencies of these two types of bulbs for converting electric energy into light?
Suppose a battery operates a 2.25 W electric clock for 19.5 months. 1. What is the available energy content, in joules, of the battery? 2. How many years can a battery that supplies 7.75 × 104 J run a pocket calculator that consumes energy at the rate of 1.05 × 10-3 W?
An 11 W LED light bulb has an efficiency of 30 %. What amount of energy is wasted if the bulb is operated continuously for 1 minute?
A 9 W led lightbulb emits the same light as a 60 W standard lightbulb. If a power company charges 10 cents per kW.h, then how much money do you save by using the led lightbulb instead of the standard lightbulb for 30 days?
Question 7: Certain areas in Arizona, Nevada, California and Texas can have up to 4000 sunny hours a year. The fact that these vast lands are less populated and agriculturally not suitable makes them ideal for solar power plants. Though most commercial solar panels have efficiencies from 15% to 20%, researchers have now developed solar cells with efficiencies approaching 50%. If you are asked to plant a solar energy system in these areas using the newest technology, how much land do you need to produce enough energy for the US. Make the conservative assumptions that the average light energy landing to the Earth' surface is 1.0 cal/(cm2 min). An estimate for the US energy consumption by major sources is given below. U.S. primary energy consumption by major sources, 1950-2019 quadrillion British thermal units 110 100 90 80 70 60 50 40 30 20 10 1950 1955 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 2010 2015 renewables nuclear petroleum natural gas coal
Every day a certain household uses a 3,3 kW electric stove for 72 minutes, six 6 hours each and miscellaneous appliances amounting to 1,6 kW h. The 3 kW hot w ninutes during the day. If electricity costs 35 c a kWh
it the minimum average power? 13. An energy-efficient fluorescent lightbulb operating at power Pı = 28 W can produce the same level of brightness as a conventional incandescent lightbulb operating at power P, 100 W. Lifetime of the energy-efficient bulb is T = 10000 h, and its purchase price is B1 = $4.50. Lifetime of the conventional bulb is T2 = 750 h, and its purchase price is B2 = $0.42. Suppose electrical energy costs R = $0.20/kWh, i.e. 20 cents per kilowatt- hour. a) Calculate the total cost of using energy-efficient bulbs over 10,000 hours. b) Calculate the total cost of using conventional bulbs over 10,000 hours. Note that you must include both the cost of purchasing the bulbs and the cost of energy.
A house has 3 tubelights, 2 fans and a television. Each tubelight draws 40 W. The fan draws 80 W and the television draws 60 W. On an average, all the tubelights are kept on for five hours, two fans for 12 hours each and the television for five hours a day. Find the cost of electric energy used in 30 days at the rate of Rs. 3.00 per KWH.
Problem Six. The sun radiates with a power of 4.00 x 104º W. Suppose PG&E charges $0.31 per kW h. How much would PG&E charge to run the sun for 1.0 micro second? Give an answer in trillions of dollars. (Note: 1 kWh = 3.6 x 10° J) 10.) (A) 27 (В) 34 (С) 51 (D) 64 (E) 72
