Feed Water Enthalpy Calculator

Calculate Feed Water Enthalpy (H)



Formula

The formula to calculate the Feed Water Enthalpy (H) is:

\[ H = \dot{m} \cdot h \]

Where:

Definition

Example

Let's say the mass flow rate (\(\dot{m}\)) is 2 kg/s, and the specific enthalpy (h) is 500 kJ/kg. Using the formula:

\[ H = 2 \cdot 500 = 1000 \, \text{kJ} \]

So, the feed water enthalpy is 1000 kJ.

Enthalpy of Feed Water

Definition: The enthalpy of feed water is the total heat content of the water used in a boiler system.

Formula: \( h = c_p \cdot T \)

Example: \( h = 1 \cdot 85 \)

Specific Enthalpy of Water

Definition: The specific enthalpy of water is the enthalpy per unit mass of water.

Formula: \( h = u + p \cdot v \)

Example: \( h = 200 + 100 \cdot 0.001 \)

Enthalpy of Hydration

Definition: The enthalpy of hydration is the heat change that occurs when one mole of an ion is dissolved in water to form an infinitely dilute solution.

Formula: \( \Delta H_{hydration} = \Delta H_{solution} - \Delta H_{lattice} \)

Example: \( \Delta H_{hydration} = -50 - (-150) \)
