Which of the following equations best expresses conservation of mass for steady, incompressible flow between two sections of a pipe having cross-sectional areas A1A_1 and A2A_2 and flow speeds v1v_1 and v2v_2, respectively? (a) A1v1=A2v22A_1 v_1 = \dfrac{A_2 v_2}{2} (b) A1v1=A2v1A_1 v_1 = A_2 v_1 (c) A1v1=A2v2A_1 v_1 = A_2 v_2 (d) A1v1=(A1+A2)v2A_1 v_1 = (A_1 + A_2) v_2
