Thermodynamics

isentropic stagnation state

Physics; Thermodynamics

The stagnation state in which the stagnation process is reversible as well as adiabatic or isentropic. The entropy of a fluid remains constant during an isentropic stagnation process.

third law of thermodynamics

Physics; Thermodynamics

It states that the entropy of a pure crystalline substance is zero at absolute zero degree temperature.

ignition temperature

Physics; Thermodynamics

The minimum temperature a fuel must be brought to in order start the combustion.

specific heat at constant pressure

The energy required to raise the temperature of the unit mass of a substance by one degree as the pressure is maintained constant. Constant pressure or Cp is a measure of the variation of enthalpy of ...

throttling valves

Physics; Thermodynamics

Any kind of flow-restricting devices that cause a significant pressure drop in the fluid. Some familiar examples are ordinary adjustable valves, capillary tubes, and porous plugs. Unlike turbines, ...

thermal efficiency

Physics; Thermodynamics

A measure of the performance of a heat engine which is the fraction of the heat input to the heat engine that is converted to net work output.

thermodynamic temperature

Physics; Thermodynamics

A temperature scale that is independent of the properties of the substances used to measure temperature. This temperature scale is called the Kelvin scale, and the temperatures on this scale are ...
