Consider the velocity field = A(x4 - 6x2y2 + y4) + A(4xy3 - 4x3y) in the xy plane, where A = 0.34 m-3 · s-1, and the coordinates are measured in meters. (a) Is this a possible incompressible flow field? (b) Calculate the x-component and (c) y-component of the acceleration of a fluid particle at point (x,y) = (4, 1).

Consider an incompressible flow in cylindrical coordinates with velocity field v = Cr^(a) θ^ where C is a constant (a) Show that the flow satisfies the Navier-Stokes equations for only two values of a. (b) Given that p(r; θ; z) = p(r) only, and neglecting gravity, find the pressure distribution for each case, assuming that the pressure at r = R is p0

This question concerns the field GF(256). The modulus is P(x)=x8+x4+x3+x+1. For computing inverses in this field, you should use the table in the textbook. Please answer the following questions about arithmetic in this field. a) If p(x)=x6+x4, and q(x)=x5+x4+x3+x, what is p(x)/q(x)? b) If p(x)=x7+x6+x5+x, and q(x)=x7+x5+x4+x2, what is p(x)/q(x)?

Zn2+ and Ni2+ both react quantitatively with EDTA (Y4-) Zn2+ + Y4- → ZnY2- Ni2+ + Y4- → NiY2- The reagent 2,3-dimercapto-1-propanol (Z) reacts with the zinc-EDTA complex to liberate EDTA but it does not react with the nickel-EDTA complex. ZnY2- + Z → ZnZ2+ + Y4- NiY2- + Z → N.R. 50.00 mL of a sample solution that contains Ni2+ and Zn2+ are mixed with 50.00 mL of 0.01981 M EDTA. The excess EDTA is titrated with 0.02010 M...
