The Rusk's own fairly large house near San Francisco and the following spreadsheet shows their month to month power use for two years.
1. What is their monthly average power use?
Extra point: Why do you think their use peaks twice a year?
2. Calculate the size of the solar PV system (kWh DC STC) they will need in order to have a zero dollar electricity bill annually (use an average over the two years). Assume that you are using 14.9% efficient panels with an 80% derating factor. Also assume that your inverter is 95% efficient. Use an average solar insolation of 5.5kW/day for their location.
3. Assume this system will be mounted on the roof. How big will the area of solar collector be? Is this a reasonable size for a house (i.e. are roofs actually this big)?
4. What is the AC, PTC per square meter for the system? Assume that the 80% derating factor gets you from DC, STC to DC, PTC.
Q. Explain about Napthenic Acid Corrosion? Some crude oils contain napthenic acids, which, at elevated temperatures, may contribute to more active corrosion with or without the
Angle of friction: It can be defined as the angle made by resultant of normal reaction ( R ) and limiting force of friction ( F ) with normal reaction ( R ). Let,
The mass flow rate is 28kg/s in an axial flow gas turbine that develops 3.5MW. The stagnation conditions are 780KPa and 730 deg.C. at the entry. At the exit of the nozzle, the stat
String Vibration Fixed Ends In case of the vibrations of a string, both its ends at x = 0 and x = L may be permanently fixed; y (x = 0) = 0 , and y (x = L) = 0 at all t
Switch Assembly: A switch assembly consists of four rails. The two outer rails are known as the stock rails. The two inner rails are called tongue rails. One stock rail and o
Rigid and linearly elastic material: A rigid material is one which is having no strain regardless of the applied stress. A linear elastic material is one in which strain is
Q. Define Zirconium and its alloys? Zirconium and its alloys were developed primarily for the nuclear industry, but have found many industrial corrosion-resistant applications
