Heat Loss Formula:
From: | To: |
Definition: This calculator estimates the heat loss from a storage tank based on the heat transfer coefficient, surface area, and temperature difference.
Purpose: It helps engineers and facility managers determine the thermal energy loss from storage tanks to improve insulation and energy efficiency.
The calculator uses the formula:
Where:
Explanation: The heat loss is directly proportional to the U-value, surface area, and temperature difference.
Details: Accurate heat loss estimation helps in designing proper insulation, reducing energy costs, and maintaining desired temperatures in storage tanks.
Tips: Enter the U-value (depends on insulation), surface area of the tank, and temperature difference between the tank contents and ambient environment.
Q1: What is a typical U-value for insulated tanks?
A: Well-insulated tanks typically have U-values between 0.2-0.6 W/m² K, while uninsulated tanks can be 5-10 W/m² K.
Q2: How do I calculate surface area for cylindrical tanks?
A: For a cylinder: \( A = 2\pi r h + 2\pi r^2 \) (side area + top and bottom).
Q3: Should I use °C or K for temperature difference?
A: Both work since ΔT is the same in Celsius and Kelvin (1°C = 1K difference).
Q4: How can I reduce heat loss from my tank?
A: Improve insulation (lower U-value), reduce surface area (use larger tanks), or minimize temperature difference.
Q5: Does this account for heat loss through supports/pipes?
A: No, this calculates only the main tank surface loss. Additional calculations are needed for ancillary components.
