The image above represents the hydrostatic pressure of a dam. To solve the hydrostatic pressure of a dam, two essential parameters are needed, and these parameters are **Specific Weight of Water (Î³) and Depth of water (h).**

The formula for calculating hydrostatic pressure of a dam:

H_{n}Â =Â ^{Î³hÂ²}Â /Â _{2}

Where:

H_{n}Â = Hydrostatic Pressure of a Dam

Î³ = Specific Weight of Water

h = Depth of Water

Let’s solve an example;

Find the hydrostatic pressure of a dam when the specific weight of water is 10 and the depth of water is 5.

This implies that;

Î³ = Specific Weight of Water = 10

h = Depth of Water = 5

This means, H_{n}Â =Â ^{Î³hÂ²}Â /Â _{2}

H_{n}Â =Â ^{(10)(5)Â²}Â /Â _{2}

That is, H_{n}Â =Â ^{10(25)}Â /Â _{2}

H_{n}Â =Â ^{250}Â /Â _{2}

H_{n} = 125

Therefore, the **hydrostatic pressure of the dam**Â is **125**.

**Calculating the Specific Weight of Water when the Hydrostatic Pressure of the Dam and the Depth of Water are Given**

Î³ = ^{Hn x 2} / _{h2}

Where;

Î³ = Specific Weight of Water

H_{n}Â = Hydrostatic Pressure of a Dam

h = Depth of Water

Let’s solve an example;

Find the specific weight of water when the hydrostatic pressure of a dam is 30 and the depth of water is 6.

This implies that;

H_{n} = Hydrostatic Pressure of a Dam = 30

h = Depth of Water = 6

Î³ = ^{Hn x 2} / _{h2}

Then, Î³ = ^{30 x 2} / _{62}

Î³ = ^{60} / _{36}

Î³ = 1.667

Therefore, theÂ **specific weight of waterÂ **is** 1.667.**

**Calculating the Depth of Water when the Hydrostatic Pressure of the Dam and the Specific Weight of Water are Given**

h = âˆš^{Hn x 2} / _{Î³}

Where;

h = Depth of Water

H_{n}Â = Hydrostatic Pressure of a Dam

Î³ = Specific Weight of Water

Let’s solve an example;

Find the depth of water when the hydrostatic pressure of a dam is 12 and the specific weight of water is 4.

This implies that;

H_{n} = Hydrostatic Pressure of a Dam = 12

Î³ = Specific Weight of Water = 4

h = âˆš^{Hn x 2} / _{Î³}

h = âˆš^{12 x 2} / _{4}

So, h = âˆš^{24} / _{4}

h = âˆš6

h = 2.449

Therefore, theÂ **depth of waterÂ **isÂ **2.449.**
