1. Use Table A.IV.4(SI) to find the dynamic viscosity of air
at the temperatures of 100, 300, 400, 600, 800, and 1000 K. Air is the
atmospheric pressure. Plot the viscosities versus temperature and describe the
2. The velocity components of a two dimensional steady ideal
fluid flow (frictionless and incompressible) are given as Vx = axy
and Vy = by2 where coefficients a and b are constants.
Find the pressure gradient in terms of a, b, x, and y. Find the value of the
pressure gradient for a = b = 1 at point x = y = 1.
