During the winter, the inside of an average house is maintained at 20 ºC, while the outside temperature is 0 ºC. Assuming that the only mechanism of heat transfer is conduction, the walls are 10 cm thick and the heat conductivity of the walls is \(0.5 W/Km\). Calculate the heat flux from the room to the surroundings in \(W/m^2\). ______
What are the main advantages of a solar tower power plant? Note that more than one correct answer is possible.
Which one of the following methods cannot be used as a cooling method using solar thermal techniques?
A hotel installation near you wants to cover their water heating demand by solar energy. However, they want to know first if it is possible. The hotel needs 1500 L/day of warm water every day and the water has to be heated from 10 to 60 ºC. The specific heat capacity of water is \(4.18 J/gK\). Assume an irradiance of \(1000 W/m^2\) for 3 equivalent sun hours and an efficiency of 70% for the installation.How much energy does the system need to produce per day to meet the warm water demand? Give your answer in kWh/day.If the hotel has \(30m^2\) available for this application, what is the maximum percentage of the warm water demand that can be covered by solar energy? ______
