From: | To: |
Definition: This calculator estimates the number of tubes that can fit in a heat exchanger bundle with triangular pitch arrangement based on the bundle diameter and pipe outer diameter.
Purpose: It helps engineers and designers determine the optimal tube count for heat exchanger designs.
The calculator uses the formula:
Where:
Explanation: The formula is an empirical relationship that estimates tube count based on the ratio of bundle diameter to tube diameter.
Details: Accurate tube count estimation is crucial for heat exchanger design, affecting heat transfer efficiency, pressure drop, and mechanical integrity.
Tips: Enter the bundle diameter and pipe outer diameter in meters. Both values must be > 0.
Q1: What is triangular pitch in heat exchangers?
A: Triangular pitch refers to the arrangement where tubes are placed in equilateral triangles, which is common for maximizing tube count and heat transfer.
Q2: How accurate is this formula?
A: This is an empirical formula that provides a good estimate but actual tube counts may vary based on specific design constraints.
Q3: What's a typical bundle diameter range?
A: Bundle diameters typically range from 0.1m for small exchangers to over 2m for large industrial units.
Q4: Does this account for tube sheet layout?
A: The formula provides an estimate but final tube counts should be verified with detailed tube sheet layout.
Q5: Can this be used for square pitch arrangements?
A: No, this formula is specifically for triangular pitch arrangements.
