using the theorem of three moments, find all the reactions and supports
(An ellipsoidal trapping region for the Lorenz equations) Show that there is a certain ellipsoidal region E of the form rx2 + σy2 + σ(z − 2r)2 ≤ C such that all trajectories of the Lorenz equations eventually enter E and stay in there forever. For a much stiffer challenge, try to obtain the smallest possible value of C with this property.
A) In a factory, an s-type pitot tube was used to calculate the velocity of dry air for a point
inside a stack.
Calculate the velocity at that point (ft/sec) using following conditions:
●
•
•
Pressure = 30.23 ± 0.01 in Hg (ambient)
Pitot tube coefficient = 0.847 ± 0.03
Temperature = 122 ± 0.1 F (stack)
Temperature = 71.2 ± 0.1 F (ambient)
AP = 0.324 ± 0.008 in H2O (pitot tube)
•
AP = 0.891 ± 0.002 in H2O (stack)
B) Find the dominant error(s) when determining precision for the problem.
C) For part A, what is the precision in ft/sec for the velocity?
