The image above represents pouring speed.

To compute for poring speed, three essential parameters are needed and these parameters are **Co-efficient for friction (μ), Acceleration due to Gravity (g) **and **Rated head static (H _{s}).**

The formula for calculating pouring speed:

v = μ√(2gH_{s})

Where:

v = Pouring Speed

μ = Co-efficient for Friction

g = Acceleration due to Gravity

H_{s} = Rated Static Head

Let’s solve an example;

Find the pouring speed when the co-efficient for friction is 14, acceleration due to gravity is 9 and rated static head is 16.

This implies that;

μ = Co-efficient for Friction = 14

g = Acceleration due to Gravity = 9

H_{s} = Rated Static Head = 16

v = μ√(2gH_{s})

v = 14 x √(2 x 9 x 16)

v = 14 x √(288)

v = 14 x 16.97

v = **237.58**

Therefore, the **pouring speed **is **237.58 m/s.**

**Calculating the Co-efficient for Friction when the Pouring Speed, the Acceleration due to Gravity and the Rated Static Head is Given.**

μ = ^{v} / _{√(2gH}_{s})

Where;

μ = Co-efficient for Friction

v = Pouring Speed

g = Acceleration due to Gravity

H_{s} = Rated Static Head

Let’s solve an example;

Find the co-efficient for friction when the pouring speed is 24, the acceleration due to gravity is 9 and the rated static head is 11.

This implies that;

v = Pouring Speed = 24

g = Acceleration due to Gravity = 9

H_{s} = Rated Static Head = 11

μ = ^{v} / _{√(2gH}_{s})

μ = ^{24} / _{√(2 x 9 x 11)}

μ = ^{24} / _{√198}

μ = ^{24} / _{14.07}

μ = 1.70

Therefore, the **co-efficient for friction **is **1.70.**
