  2. Flow distribution in manifolds - Wikipedia

    en.wikipedia.org/wiki/Flow_distribution_in_manifolds

    f = 64/Re for laminar flow where Re is the Reynolds number. The frictional resistance, = using Poiseuille's law. Since they have same diameter and length in Fig. 3, their resistances are same, R 2 = R 3. Thus the velocities should be equal in two outlets or the flow rates should be equal according to the assumptions.

    en.wikipedia.org/wiki/Symplectic_manifold

    Symplectic manifolds arise from classical mechanics; in particular, they are a generalization of the phase space of a closed system. [1] In the same way the Hamilton equations allow one to derive the time evolution of a system from a set of differential equations, the symplectic form should allow one to obtain a vector field describing the flow of the system from the differential of a ...

    This is a table of 1962 United States Tri-Service aircraft designation system with selected letter sequences and number. Two previous USAF/AAF/AAC number series are included due to their impact and partial incorporation into the tri-service system (A, B, C, F and O reset to one, but # carryover existed).

  7. Pennsylvania Railroad class B6 - Wikipedia

    en.wikipedia.org/wiki/Pennsylvania_Railroad_class_B6

    The Pennsylvania Railroad's class B6 was its most successful class of switcher locomotive, or as the PRR termed them "shifter". The PRR preferred the 0-6-0 wheel arrangement for larger switchers, whereas on other railroads the 0-8-0 gained preference. The PRR generally used 2-8-0s when larger power was required.

  9. Cauchy momentum equation - Wikipedia

    en.wikipedia.org/wiki/Cauchy_momentum_equation

    Here j and s have same number of dimensions N as the flow speed and the body acceleration, while F, being a tensor, has N 2. [ note 1 ] In the Eulerian forms it is apparent that the assumption of no deviatoric stress brings Cauchy equations to the Euler equations .
