Bundle Diameter Formula:
From: | To: |
Definition: Bundle Diameter refers to the diameter of the tube bundle within the heat exchanger.
Purpose: It helps engineers determine the size of the tube bundle for heat exchanger design and manufacturing.
The calculator uses the formula:
Where:
Explanation: The bundle diameter is calculated by multiplying the number of tubes in the center row by the tube pitch (center-to-center spacing).
Details: Proper bundle diameter estimation is crucial for heat exchanger design, ensuring proper fit within the shell and optimal heat transfer performance.
Tips: Enter the number of tubes in the vertical row and the tube pitch (default 0.023m). All values must be > 0.
Q1: What is tube pitch?
A: Tube Pitch in a heat exchanger refers to the center-to-center spacing between adjacent tubes in a tube bundle.
Q2: How do I determine the number of tubes in vertical row?
A: This is typically determined by the heat exchanger layout and the number of tubes that align vertically in the center of the bundle.
Q3: What's a typical tube pitch value?
A: Common tube pitch values range from 1.25 to 1.5 times the tube diameter, often around 0.023m for many applications.
Q4: Does this calculation work for all tube layouts?
A: This formula works best for square and rotated square tube layouts. Triangular layouts may require adjustment factors.
Q5: How does bundle diameter affect heat exchanger performance?
A: Bundle diameter impacts shell-side flow velocity, pressure drop, and heat transfer coefficients, making it a critical design parameter.
