The image above represents enthalpy for wet steam.

To compute for enthalpy for wet steam, three essential parameters are needed and these parameters are **Dryness Fraction (x), Enthalpy of Water (h _{f})** and

**Enthalpy of Vapourization (h**

_{fg}).The formula for calculating enthalpy for wet steam:

h = h_{f} + xh_{fg}

Where:

h = Enthalpy of Wet Steam

x = Dryness Fraction

h_{f} = Enthalpy of Water

h_{fg} = Enthalpy of Vapourization

Let’s solve an example;

Find the enthalpy of wet steam when the dryness fraction is 4, the enthalpy of water is 6 and the enthalpy of vapourization is 8.

This implies that;

x = Dryness Fraction = 4

h_{f} = Enthalpy of Water = 6

h_{fg} = Enthalpy of Vapourization = 8

h = h_{f} + xh_{fg}

h = 6 + 4 x 8

h = 6 + 32

h = **38**

Therefore, the **Enthalpy of Wet Steam **is **38 J/Kg.**

**Calculating the Dryness Fraction when the Enthalpy of Wet Steam, the Enthalpy of Water and the Enthalpy of Vapourization is Given.**

x = ^{h – hf} / _{hfg}

Where;

x = Dryness Fraction

h = Enthalpy of Wet Steam

h_{f} = Enthalpy of Water

h_{fg} = Enthalpy of Vapourization

Let’s solve an example;

Find the dryness fraction when the enthalpy of wet steam is 14, the enthalpy of water is 8 and the enthalpy of vapourization is 2.

This implies that;

h = Enthalpy of Wet Steam = 14

h_{f} = Enthalpy of Water = 8

h_{fg} = Enthalpy of Vapourization = 2

x = ^{h – hf} / _{hfg}

x = ^{14 – 8} / _{2}

x = ^{6} / _{2}

x = 3

Therefore, the **dryness fraction **is **3.**

**Calculating the Enthalpy of Water when the Enthalpy of Wet Steam, the Dryness Fraction and the Enthalpy of Vapourization is Given.**

h_{f} = h – xh_{fg}

Where:

h_{f} = Enthalpy of Water

h = Enthalpy of Wet Steam

x = Dryness Fraction

h_{fg} = Enthalpy of Vapourization

Let’s solve an example;

Find the enthalpy of water when the enthalpy of wet steam is 20, the dryness fraction is 4 and the enthalpy of vapourization is 3.

This implies that;

h = Enthalpy of Wet Steam = 20

x = Dryness Fraction = 4

h_{fg} = Enthalpy of Vapourization = 3

h_{f} = h – xh_{fg}

h_{f} = 20 – (4)(3)

h_{f} = 8

Therefore, the **enthalpy of water **is **8 J/Kg.**

**Calculating the Enthalpy of Vapourization when the Enthalpy of Wet Steam, the Dryness Fraction and the Enthalpy of Water is Given.**

h_{fg} = ^{h – hf} / _{x}

Where:

h_{fg} = Enthalpy of Vapourization

h = Enthalpy of Wet Steam

x = Dryness Fraction

h_{f} = Enthalpy of Water

Let’s solve an example;

Find the enthalpy of vapourization when the enthalpy of wet steam is 32, the dryness fraction is 10 and the enthalpy of water is 2.

This implies that;

h = Enthalpy of Wet Steam = 32

x = Dryness Fraction = 10

h_{f} = Enthalpy of Water = 2

h_{fg} = ^{h – hf} / _{x}

h_{fg} = ^{32 – 2} / _{10}

h_{fg} = ^{30} / _{10}

h_{fg} = 3

Therefore, the **enthalpy of vapourization** is **3 J/Kg.**
