Net thermal energy formula
WebA parameter, R, is defined as the ratio of thermodynamic loss rate to capital cost K as follows: The value of R generally depends on whether it is based on energy loss rate (in which case it is denoted Ren ), or exergy loss rate ( Rex ), as follows: Note that one can consider four main thermodynamic loss rates [5]: energy ( en ); exergy ( ex ... WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides …
