Because energy can take several different forms, it is necessary for us to understand the forms that are of primary interest to a chemical engineer. These forms are briefly described in the following section.<\/p>\n\n\n\n
Three primary forms of energy are encountered in a chemical process [1]:<\/p>\n\n\n\n
1.<\/strong> Kinetic energy<\/em> (KE<\/em>)\u2014Energy associated with motion. Kinetic energy of a body of mass m<\/em> and velocity v<\/em> is \u00bdmv<\/em>2<\/sup>. Clearly, a body moving at a higher velocity has higher kinetic energy than one of equal mass but lower velocity.<\/p>\n\n\n\n 2.<\/strong> Potential energy<\/em> (PE<\/em>)\u2014The energy associated with position. Potential energy of a body of mass m<\/em> is mgh<\/em>, where g<\/em> is acceleration due to gravity and h<\/em>, its distance from the earth\u2019s surface.<\/p>\n\n\n\n 3.<\/strong> Internal energy<\/em> (U<\/em>)\u2014Stored energy associated with atomic and molecular structure and characteristics.<\/p>\n\n\n\n Other forms of energy, such as electric and magnetic field energies, are typically not of interest in chemical processes [2] and are not included in the analysis presented in this book. The energy of a system,\u00a0E<\/em>, comprises these three primary forms. The first two forms of energy (kinetic and potential) constitute the\u00a0mechanical energy<\/em>\u00a0of the system.<\/p>\n","protected":false},"excerpt":{"rendered":" Because energy can take several different forms, it is necessary for us to understand the forms that are of primary interest to a chemical engineer.
