Temperature Difference

Some articles on temperature, temperature difference, difference, temperatures, temperature differences, differences:

Stirling Engine - Theory - Operation
... A change in gas temperature will cause a corresponding change in gas pressure, while the motion of the piston causes the gas to be alternately expanded and compressed ... described by the gas laws which describe how a gas' pressure, temperature and volume are related ... The efficiency of Stirling machines is linked to the environmental temperature a higher efficiency is obtained when the weather is cooler, thus making this type of engine less interesting in places ...
Nucleate Boiling - Mechanism
... When the temperature difference is between approximately 4 °C (7.2 °F) to 10 °C (18 °F) above TS, isolated bubbles form at nucleation sites and separate from the surface ... After this point, the heat transfer coefficient starts to reduce as the surface temperature is further increased although the product of the heat transfer coefficient and the ... When the relative increase in the temperature difference is balanced by the relative reduction in the heat transfer coefficient, a maximum heat flux is ...
Minimum Resolvable Temperature Difference
... Minimum resolvable temperature difference (MRTD) is a measure for assessing the performance of infrared cameras, and is inversely proportional to the ... Typically, an operator is asked to assess the minimum temperature difference at which a 4 bar target can be resolved ... This minimum difference will change with the spatial frequency of the bar target used ...
Automotive Thermoelectric Generator - Operation Principles
... The temperature difference between the two surfaces of the thermoelectric module(s) generates electricity using the Seebeck Effect ... With exhaust temperatures of 700°C (~1300°F) or more, the temperature difference between exhaust gas on the hot side and coolant on the cold side is ... This temperature difference is capable of generating 500-750 W of electricity ...
Thermoelectricity - Seebeck Effect
... The Seebeck effect is the conversion of temperature differences directly into electricity and is named after the Baltic German physicist Thomas Johann Seebeck ... This was because the metals responded differently to the temperature difference, creating a current loop and a magnetic field ... law by generating currents even in the absence of voltage differences (or vice versa) the local current density is given by where is the local ...

Famous quotes containing the words difference and/or temperature:

    O, the difference of man and man!
    To thee a woman’s services are due.
    William Shakespeare (1564–1616)

    The bourgeois treasures nothing more highly than the self.... And so at the cost of intensity he achieves his own preservation and security. His harvest is a quiet mind which he prefers to being possessed by God, as he prefers comfort to pleasure, convenience to liberty, and a pleasant temperature to that deathly inner consuming fire.
    Hermann Hesse (1877–1962)
