# Water flowing out of a -diameter faucet fills a bottle in . At what distance below the faucet has the water stream narrowed to diameter?

The distance below stream the faucet water is

See the step by step solution

## Step :1 Introduction

Diameter of the faucet 1 is

Radius of the faucet is

Water flow at the speed of

Acceleration due to gravity is

Diameter of the faucet when it is narrowed

Radius of the faucet

Water flow after the faucet is narrowed

From the equation, continuity is

Speed of the water in the narrowed faucet is

The pressure difference is the same in both of the faucets. Therefore, from Bernoulli's equation

## Step :2 Substituution
