Solving the incompressible Navier-Stokes equations numerically is a unique challenge because of the absence of direct link between pressure and density. As a workaround, the pressure equation must be derived from the velocity field and corrected in each iteration to ensure divergence free condition is satisfied.

Marker-and-cell (MAC) algorithm is the most common algorithm used to numerically solve in compressible Navier-Stokes equations. What is the main characteristic of this algorithm?

answer:

ask me the quest

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
