1)
Consider the 2D flow in a rectangular box as shown.
The velocity
field
is given by u=3 x, v=3 y
The volume flow rate (per unit span)
out of the box through the top face, AB, is
a)
6
b) 3
c)
0
d) 3
e) 6
2)
For the same case as in Problem 1) :
The volume flow rate out of the box through the front
face, DA , is
3)
The density of 10W30 motor oil, in kg/m^3, is closest to
4)
A
2D velocity field is given by u=3 y + 6 x; v= 3 x  6 y
where
x
and y are in meters and u,v
in m/s
The vorticity component in the +z direction is
