An experimentalist has measured the u-velocity component of a steady, two-dimensional flow field. it is approximated by = 3xy + x + 10 it is also known that the v-velocity is zero along the line y=0.
a) (3 points) find an expression for the v-velocity in the entire field
b) (3 points) find an expression for the streamfunction, , for this flow
c) (4 points)determine the location of any stagnation points in the flow (stagnation means vr=0)
d) calculate the acceleration field (ax and ay) for this flow field.

answer:

the answer is d

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
