One of the most frequent uses made of a steam table is to find the enthalpy, or total heat, of superheated steam. For pressures above 250 pounds, the ordinary tables require a double interpolation as the values are given only in increments of five or ten pounds pressure and tea, twenty,...
Often used in the context of thermodynamic cycles and state functions. In a steam turbine, the enthalpy drop of steam correlates with the turbine's energy output. 7 Energy Broad concept encompassing the capacity to do work or produce heat. Kinetic energy of moving objects or potential energy du...
