This paper offers an analytical formulation of the two errors embodied in the momentum theory. The first one originates from the use of the differential form of the axial momentum equation and the second one originates from the linearization of the tangential velocity terms. Both errors are evaluated by comparing the axial velocity at the disk as predicted by the momentum theories with the one obtained thorough a semianalytical actuator disk method based on the exact solution of the flow. Several cases characterized by different values of the thrust and advance coefficient are analyzed, and the range of validity of the momentum theories is discussed in depth.
