Effectiveness Of Heat Exchanger In Cross Flow When Both Fluids Are Unmixed Equation:
| From: | To: |
The effectiveness of a heat exchanger in cross flow when both fluids are unmixed is a measure of how well the heat exchanger performs relative to its maximum possible performance. It represents the ratio of actual heat transfer to the maximum possible heat transfer.
The calculator uses the cross flow heat exchanger effectiveness equation:
Where:
Explanation: This equation calculates the effectiveness for cross flow heat exchangers where both fluids remain unmixed throughout the heat transfer process.
Details: Calculating heat exchanger effectiveness is crucial for designing efficient heat transfer systems, optimizing energy usage, and ensuring proper thermal performance in various engineering applications.
Tips: Enter the Number of Transfer Units (NTU) and Heat Capacity Ratio (C). NTU must be greater than 0, and C must be between 0 and 1 (inclusive).
Q1: What is the range of effectiveness values?
A: Effectiveness values range from 0 to 1, where 0 indicates no heat transfer and 1 indicates maximum possible heat transfer.
Q2: What does NTU represent?
A: NTU (Number of Transfer Units) represents the non-dimensional heat transfer size of the exchanger, calculated as the ratio of overall thermal conductance to the smaller heat capacity rate.
Q3: What is heat capacity ratio?
A: Heat capacity ratio (C) is the ratio of the minimum heat capacity rate to the maximum heat capacity rate (Cmin/Cmax).
Q4: When is this specific equation applicable?
A: This equation is specifically for cross flow heat exchangers where both fluids remain unmixed throughout the heat transfer process.
Q5: Are there limitations to this equation?
A: This equation is specifically designed for cross flow configurations with both fluids unmixed and may not be accurate for other heat exchanger configurations.
