Document Summary

You can never achieve 100% even though energy is conserved. Thermodynamics is the science of energy: engineering thermodynamics applies to the design and analysis of energy conversion systems, energy conversion between system or within system. Thermodynamics emerged as a science with the steam engine. Transfer the energy of the fire to do mechanical work, this however involves lots of energy. Working fluid: transferring energy from one source or another to do some useful mechanical work. Trying to use energy from another source to do useful mechanical work in another part. Pressure: force per unit area, pascal, n/m2: absolute pressure: measured relative to absolute zero pressure, gage/vacuum pressure: measured relative to atmospheric pressure. In thermodynamics we deal almost exclusively with absolute pressure. Unless the problem explicitly states gauge pressure is used, assume that the pressure is absolute. Temperature: absolute scale in the si system is the kelvin scale, t(k) = t(oc) + 273. 15.
