If we wanted to supply all the electricity needs for New York City (NYC), with a popula- tion of about 10 million people, using photovoltaics technology, how much land area would we need? What other elements would be required for such an idea to work for NYC? How large of an investment would this involve, and how would the price of electricity in ¢ per kWeh have to increase in order to recover that investment in 10 years at an interest rate of 8%? For comparison, the average New Yorker paid 12¢/kWeh in 2002.
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

The power transmitted of two pulleys connected by an open belt or crossed belt is a) directly proportional to their diameters; b) inversely proportional to their diameters; proportional to the square of their diameters; c) directly d) inversely proportional to the square of their diameters. 2. Two pulleys of diameters d1 and d2 and at distance x apart are connected by means of an open belt drive. The length of the belt is: a) π/2 (d: + d₂) 2x + (d: + dz)/4x; b) n/2 (d₁-dz) 2x + (di-dz)/4x; c) n/2 (d: +d₂) 2x + (di-d₂}/4x; d) π/2 (d₁-də) 2x + (d: +d₂)²/4x. 3. In a cone pulley, if the sum of radii of the pulleys on the driving and driven shafts is constant, then: a) open belt drive is recommended; b) cross belt drive is recommended; c) both open belt drive and cross belt drive are recommended; d) the drive is recommended depending upon the torque transmitted. 4. Due to not slip of the belt, the power transmitted of the belt drive:…
The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation? Mcyl 411.7 g, malum 46.5 g, malum+water = 175 g Can you find: mwater =? g Twater = Talum = 20°C (water and cup of room temperature) 90°C, T; = 35°C (hot cylinder and cool "cylinder+cup+water" temperatures) Tcyl kCal Calum = 0.22, Cwater 1 (specific heat of water and aluminum, measured in units kg-°C What are we looking for is Ccul - How we find it? Plug all the numbers into the equation (1), Ccul will be one unknown which you can calculate from the equation. Important, convert all the masses from grams to kilograms! After you find Ccyl, compare it to known value for the copper 0.093(our cylinder is made out of copper). |Ceyl -0.093| % : · 100% 0.093

Qout W H.P. in SOURCE A Carnot heat pump is used to maintain the temperature inside a building at 20 °C. Significantly, the colder it gets outside, the more heat is lost through the walls and windows of the building. Assume that 95 kW of heat are lost for each degree difference between the outside and the inside temperature. That means that the colder it gets, the harder the heat pump will need to work. However, for safety reasons, the controller circuit for the heat pump limits its electrical power consumption to 205 kW. What's the coldest it can get outside before the heat pump can't maintain the building temperature adequately? °C in
