Learn MoreSpecific heat capacity. The specific heat capacity of a substance is the quantity of heat energy required to raise the temperature of 1 kg of the substance by 1°C.The symbol used for specific heat capacity is c and the units are J/(kg °C) or J/(kg K). (Note that these units may also be written as J kg–1 °C–1 or J kg–1 K–1).. Some typical values of specific heat capacity for the

Learn MoreThe levelized cost of energy (LCOE) is a measure of a power source that allows comparison of different methods of electricity generation on a consistent basis. The LCOE can also be regarded as the minimum constant price at which electricity must be sold in order to break even over the lifetime of the project. This can be roughly calculated as the net present value of all costs over the

Learn MoreUsing the number 1 (unity) as a base would not work either since all the powers of 1 are equal to 1. He therefore chose (1-10 -7 ) or 0.9999999 as the base from which he constructed his tables. Napier named his exponents logarithms from the Greek logos and arithmos roughly translated as ratio-number .

Learn MoreA geothermal heat pump (GHP) or ground source heat pump (GSHP) is a type of heat pump used to heat and/or cool a building by exchanging heat with ground, often through a vapor-compression refrigeration cycle.. It uses the earth all the time, without any intermittency, as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in

Learn MoreJun 16, 2014 · Numbers seem wildly off. For example look at the energy cost for producing 700 tons of concrete. That may be the amount of electrical energy used to produce the concrete but no way reflects the total amount of energy required. 700 tons / 6(cement ratio) x 1.4 MWh (per ton of cement, via the Columbia.edu) is a lot more than .4 MWh.
