Final Temperature Equation:
From: | To: |
The final temperature equation calculates the equilibrium temperature when two liquids of different temperatures are mixed, accounting for their volumes and densities. This is based on the principle of conservation of energy and heat transfer between the two substances.
The calculator uses the following equation:
Where:
Explanation: The equation calculates the weighted average temperature based on the thermal mass (volume × density) of each liquid.
Details: Accurate temperature prediction is crucial for industrial processes, chemical reactions, food preparation, and any application where temperature control is important.
Tips: Enter all volumes in gallons, densities in kg/gallon, and temperatures in °C. All values must be positive numbers.
Q1: Why use density in the calculation?
A: Density converts volume to mass, which is necessary because heat capacity depends on mass, not volume.
Q2: What if the liquids have different specific heats?
A: This simplified equation assumes similar specific heat capacities. For liquids with significantly different heat capacities, a more complex equation is needed.
Q3: Does this work for any unit system?
A: The calculator uses gallons and kg/gallon, but the equation works with any consistent units for volume and density.
Q4: What about heat loss to the environment?
A: This calculation assumes an isolated system with no heat loss. In real-world applications, you may need to account for heat transfer.
Q5: Can I use this for gases?
A: While the principle is similar, gases typically require accounting for pressure changes and different heat capacities.
