Definition: This calculator estimates the number of tubes that can fit in a heat exchanger bundle with two-pass square pitch configuration based on bundle diameter and pipe outer diameter.
Purpose: It helps heat exchanger designers determine the optimal tube count for given dimensions.
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 pipe diameter.
Details: Proper tube count estimation ensures efficient heat transfer, proper fluid flow, and optimal use of available space in the heat exchanger.
Tips: Enter the bundle diameter and pipe outer diameter in meters. Both values must be > 0.
Q1: What is two-pass square pitch configuration?
A: It's a tube arrangement where tubes are laid out in a square pattern and the fluid makes two passes through the exchanger.
Q2: How accurate is this formula?
A: It provides a good estimate but actual tube count may vary based on specific design constraints and manufacturing tolerances.
Q3: Can this be used for other tube arrangements?
A: No, this formula is specific to two-pass square pitch configuration. Other arrangements require different formulas.
Q4: 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.
Q5: Does this include space for baffles and supports?
A: No, additional space considerations may be needed for these components in the actual design.
