Check Your Understanding

Consider the algebraic equation for mass conservation at the end of the above video. This equation is of the form: Au1+Bu2+Cv1+Dv3=E where A,B,C,D,E are constant coefficients. From the explanation in the video, one can deduce that A=B=Δy/2. Denote the width of each cell in the x direction as Δx.

What is the value of C, the coefficient that multiples v1?

Check Your Understanding

What is the value of the coefficient E in the equation in the previous question? Assume that that the inlet velocity is 1m/s in the x direction.
