The image above represents transmissivity.

To compute for transmissivity, two essential parameters are needed and these parameters are **Saturated Thickness of Aquifer (b)** and **Hydraulic Conductivity (K).**

The formula for calculating transmissivity:

T = bK

Where:

T = Transmissivity

b = Saturated Thickness of Aquifer

K = Hydraulic Conductivity

Let’s solve an example;

Find the transmissivity when the saturated thickness of aquifer is 10 and the hydraulic conductivity is 5.

This implies that;

b = Saturated Thickness of Aquifer = 10

K = Hydraulic Conductivity = 5

T = bK

T = 10 x 5

T = 50

Therefore, the **transmissivity **is **50.**

**Calculating the Saturated Thickness of Aquifer when the Transmissivity and the Hydraulic Conductivity is Given.**

b = ^{T} / _{K}

Where;

b = Saturated Thickness of Aquifer

T = Transmissivity

K = Hydraulic Conductivity

Let’s solve an example;

Find the Saturated Thickness of Aquifer when the transmissivity is 28 and the hydraulic conductivity is 7.

This implies that;

T = Transmissivity = 28

K = Hydraulic Conductivity = 7

b = ^{T} / _{K}

b = ^{28} / _{7}

b = 4

Therefore, the **saturated thickness of aquifer **is **4.**

**Calculating the Hydraulic Conductivity when the Transmissivity and the Saturated Thickness of Aquifer is Given.**

K = ^{T} / _{b}

Where;

K = Hydraulic Conductivity

T = Transmissivity

b = Saturated Thickness of Aquifer

Let’s solve an example;

Find the hydraulic conductivity when the transmissivity is 30 and the saturated thickness of aquifer is 10.

This implies that;

T = Transmissivity = 30

b = Saturated Thickness of Aquifer = 10

K = ^{T} / _{b}

K = ^{30} / _{10}

K = 3

Therefore, the **hydraulic conductivity **is **3.**
