# Vessel Heat Loss Calculator

Introduction

Calculating heat loss in vessels is crucial for various industries to optimize energy usage and maintain operational efficiency. A vessel heat loss calculator simplifies this process, providing accurate results for informed decision-making.

**How to Use**

Using the vessel heat loss calculator is straightforward. Enter the required parameters such as vessel dimensions, material properties, and operating conditions into the designated fields. Then, click the “Calculate” button to obtain the heat loss value.

**Formula**

The formula used for calculating heat loss in vessels is based on the principles of thermal conduction and convection. The most accurate formula for this calculation is the following:

Where:

*Q*is the heat loss (W)*k*is the thermal conductivity of the material (W/mK)*L*is the length of the vessel (m)*T*1 and*T*2 are the temperatures at the inner and outer surfaces of the vessel respectively (°C)*r*1 and*r*2 are the inner and outer radii of the vessel respectively (m)

**Example Solve**

Let’s consider a cylindrical vessel with the following parameters:

- Length (L) = 2 m
- Inner radius (r1) = 0.5 m
- Outer radius (r2) = 0.6 m
- Thermal conductivity (k) = 25 W/mK
- Inner surface temperature (T1) = 150°C
- Outer surface temperature (T2) = 30°C

Plugging these values into the formula:

*Q*≈4521.95W

So, the heat loss from the vessel is approximately 4521.95 Watts.
