füüsikasuurus, mis iseloomustab soojusvahetuse teel üle kantud energiahulka, form of energy related to chaotic microscopic behaviour of a system, given by the difference between the increase of the total energy of a closed system and the work done on the system, during a process of energy transfer, difference between the increase of the total energy of a physical system and the work done on the system, provided that matter and electromagnetic energy do not cross the boundary of the system, ISQ tuletatud suurus

pinnaelemendi antud suunalise heleduse ja sama elemendi valgustustiheduse jagatis, quotient of the luminance of a surface element in a given direction by the illuminance on the surface element

vookogus, Q = dV/dt, kus V on tegelik voomaht ja t on aeg, mis kulus selle voomahul arvesti läbimiseks, flow rate, Q = dV/dt, where V is actual volume of flow and t is time taken for this volume to pass through the meter, voomuunduri ristlõiget läbinud voolava keskkonna vookoguse suhe selle ristlõike läbimiseks kulunud ajaga, ratio of the quantity of fluid passing through the cross-section of the flow sensor and the time taken for this quantity to pass through this section, mass or volume of fluid passing through the primary device per unit time, quotient of the quantity of fluid passing trough the cross-section of a conduit and the time taken for this quantity to pass through this section
