(a) Explanation The equation of continuity is used for the speed of the liquid at the smaller end of the pipe as shown here. A 2 v 2 = A 1 v 1 → v 2 = ( A 1 / A 2 ) v 1 . Given info : The cross sectional area of the first section is 10.0 cm 2 , the cross sectional area of second section is 2.50 cm 2 , and the flow speed of the liquid in the first section of the pipe is 275 cm/s . The formula for the speed of a liquid in the smaller section of the pipe is, v 2 = ( A 1 A 2 ) v 1 A 1 is cross sectional area of the first section of the pipe. A 2 is cross sectional area of the second section of the pipe. v 1 is speed of the liquid in the first section of the pipe (b) To determine The pressure of a liquid in the smaller section of the horizontal pipe.
