Nozzle efficiency is defined as
WebPropulsive efficiency [ edit] Propulsive efficiency is defined as the ratio of work done on the fluid to the propulsive power, i.e. thrust times velocity of the vehicle. In generic terms, the propulsive power can be calculated as follows: P p r o p = T × v ∞ {\displaystyle P_ {prop}=T\times v_ {\infty }} where.
