A new method is derived in this study, which is a temperature-explicit formulation of the energy equation. The enthalpy form of the energy equation is used in the method. But the final discrete form of the equation is expressed with temperature. The discretized equation from the temperature-...
Climate change could significantly affect consumer demand for energy in buildings, as changing temperatures may alter heating and cooling loads. Warming climates could also lead to the increased adoption and use of cooling technologies in buildings. We a
In addition, under the pure-H2O anolyte, the Nernst equation can be simplified to equation (6) at room temperature36 (Supplementary Note 5). The anolyte pH is ~7 owing to the use of pure H2O. We assume that the OH− concentration on the AEM surface was 1 M (that is, pH 14),...
If the flow regime is turbulent, then the relationships in the flow cannot be easily described mathematically, but the head loss may be derived by equating the shear force at the pipe wall to the change in pressure force along the pipe. This gives the D'Arcy equation: (1.44)hL=4fLDv22g...
To make an object go from a solid to a liquid or a liquid to a gas you need to add some energy. This energy is the latent heat. The energy goes into weakening the intermolecular bonds NOT into changing the temperature. The equation for the energy is: The energy needed = mass x spe...

Energy demand is only one part of the equation. Too often, operators fail to give enough attention to the supply sides of their energy expenditures. It is still rare to find an energy-sourcing specialist in a telecom operator’s procurement department, even though sizeable...
This means then that the “available wind energy is proportional to the cube of the wind speed” or wind velocity, and this statement is very important as a small change in wind speed makes a big change in the power contained within it. Wind Energy Example No1 Lets assume that we live ...
it will result in a higher PV module temperature and thus require a higher airflow rate to cool it and maintain itspower generation efficiencywithout overheating. There is a similar issue when integrating Phase Change Materials (PCM), Thus, these advanced types of DSF are more reliant on mechan...
It is very much a practical engineering equation and for this reason it is commonly reduced to the form given here where all the terms are measured in metres. A pipeline designer, for example, could use it to keep track of how the pressure head would change along a pipe system as it ...
