Step 1

Given that the radius of the bottom pipe is r1=0.0269m, the radius of the top pipe is r2=0.0588m, and the height h=3.80m. The cross sectional areas of the bottom pipe and the top pipe can be computed as shown below.

Step 2

Let v­1 and v2 be the speed of flow in the bottom pipe and top pipe respectively. The equation of continuity of the flow can be written as shown below.

Step 3

Write the Bernoulli’s equa...
