Rankineov stupanj: razlika između inačica

Posljednja izmjena od 16. ožujak 2022. u 12:24

Rankineova ljestvica je termodinamički (apsolutna) temperaturna ljestvica nazvana po škotskom inženjeru i fizičaru Williamu Johnu Macquornu Rankineu, koji ju je predložio 1859. godine.

Simbol za Rankineov stupanj je °R^[1] (ili Ra ako je potrebno kako bi se razlikovao od Rømerove i Réaumurove). Nula na Rankineovoj ljestvici je, kao i na Kelvinovoj ljestvici, je apsolutna nula, a Rankineov stupanj je jednak Fahrenheitovom stupnju. Temperatura od −459.67 °F je jednaka 0 °R. Veza između Fahrenheitove i Rankinevoe ljestvice je:

[R] = [° F] + 459,67

Nekoliko inženjerskih polja u SAD-u mjeri termodinamička temperatura koristeći Rankineovu ljestvicu.^[2] Međutim, danas se u znanstvenom svijetu, pa i u SAD-u ipak najviše koristi kelvin.^[2] Američki National Institute of Standards and Technology ne preporuča korištenje Rankineovog stupnja u NIST publikacijama.^[1]
