1. What is the Drink Cooling Equation?

The drink cooling equation estimates temperature change over time based on Newton's law of cooling. It provides a simple way to predict how quickly a drink will cool under constant conditions.

2. How Does the Calculator Work?

The calculator uses the cooling equation:

Where:

• \( \Delta T \) — Temperature change (°C)
• \( k \) — Cooling constant (°C/min)
• \( time \) — Time in minutes

Explanation: The equation assumes a linear cooling rate, which is a simplified model of the actual cooling process.

3. Importance of Cooling Calculation

Details: Understanding cooling rates helps in food safety, beverage service, and thermal management applications.

4. Using the Calculator

Tips: Enter the cooling constant (k) in °C/min and time in minutes. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is the cooling rate really constant?
A: In reality, cooling rate changes as temperature difference decreases, but this simplified model works well for short time periods.

Q2: How do I determine the cooling constant?
A: Measure temperature change over a known time period and calculate k = ΔT/time.

Q3: What affects the cooling constant?
A: Container material, ambient temperature, liquid volume, and stirring all affect k.

Q4: Can I use this for heating calculations?
A: Yes, the same principle applies - just use a positive k for cooling and negative for heating.

Q5: When is this model not accurate?
A: For long time periods, phase changes (like ice formation), or when ambient temperature changes significantly.
