1. What is a Tank Heat Loss Calculator?

Definition: This calculator estimates the heat loss from a tank surface based on the heat transfer coefficient, surface area, and temperature difference.

Purpose: It helps engineers and facility managers determine thermal energy losses from storage tanks and vessels.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Heat loss (Watts)
• \( U \) — Heat transfer coefficient (W/m²K)
• \( A \) — Surface area (m²)
• \( \Delta T \) — Temperature difference (Kelvin)

Explanation: The heat loss is calculated by multiplying the U-value by the surface area and the temperature difference between the tank contents and ambient environment.

3. Importance of Heat Loss Calculation

Details: Accurate heat loss calculations are essential for proper insulation design, energy efficiency assessments, and heating system sizing.

4. Using the Calculator

Tips: Enter the U-value (thermal transmittance), total surface area of the tank, and temperature difference between tank contents and ambient. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical U-values for tanks?
A: U-values range from 0.3-1.0 W/m²K for insulated tanks and 5-15 W/m²K for uninsulated metal tanks.

Q2: How do I calculate total surface area?
A: For cylindrical tanks: \( 2\pi r h + 2\pi r^2 \) (side + top and bottom), where r is radius and h is height.

Q3: Why use Kelvin for temperature difference?
A: The Kelvin scale gives absolute temperature differences, but since ΔT is the same in °C and K, you can use either.

Q4: Does this account for wind effects?
A: No, for outdoor tanks, wind increases heat loss. Use higher U-values for windy conditions.

Q5: How can I reduce heat loss?
A: Increase insulation thickness, use better insulating materials, or reduce the temperature difference.
