answer is given just give the solution and right answer.

3) An incompressible flow velocity field is given as 1 1 [m/s] r r where r is in meters. (a) Calculate the mass flow rate through the cylindrical surface at r =1 m from z = 0 to z =1 m as shown in Figure A (b) Show that mass is conserved in the annular control volume from r = 1 m to r = 2 m and z = 0 to z = 1 m as shown Figure B a 2 m.
