K.C.S.E Physics Q & A - MODEL 2014PP1QN11

​Figure 7 shows an incompressible fluid flowing through a pipe, A1 and A2 are the cross-sectional areas of the pipes in the larger section and smaller section of the pipe respectively, while V1 and V2 are speeds of the fluid at the two sections of the pipe.

​Derive an expression for the ratio of the speeds V2/V1 in terms of A1 and A2.
