This paper derives the equation of additional pressure from the difference of inside and outside ball liquid level and the difference of inside and outside arbitrary flexure liquid level.

The N-S equations with adoption of an actuator disk model are used to simulate the effect of turbo-propeller slipstream on high-lift systems.

Based on the results of Bayes estimations, the standard deviations for the compressive strength of RAC with strength grades of C20 and C30 were proposed.
