10. Consider square surface (side length of 0.4 m) located in the cz-plane as shown in the diagram below: Calculate the mass flux through that surface for the flow: f = poo (Im) j. Assume vo = 0.1 m/s. 11. Repeat the above calculation if f = pu Im 12. Returning to the cube in problem 5, what is the total mass flow through the surfaces of the cube for this flow f (i.e., the flow in Problem 11)? Again, take vo = 0.1 m/s y + cube in problem 5 Assume fixed mass density p =10^3 kg/m^3
