Condensate Flow Rate Calculator
How to calculate the condensate flow rate? Use our Condensate Flow Rate checker tool. Simple Enter the steam flow and steam quality into the calculator to find out condensate flow rate.
What is CFR (Condensate Flow Rate)?
The condensate flow rate (CFR) measures the amount of condensate produced in a steam system. It’s important for maintaining system efficiency and safety.
How to Use the Calculator
Input Fields:

 Steam Flow (SF): Enter the steam flow in pounds per hour.
 Steam Quality (SQ): Enter the steam quality as a percentage.
Example Input Values:

 Steam Flow: 1000 lbs/hr
 Steam Quality: 90%
How to Calculate Condensate Flow Rate
To calculate the condensate flow rate, use the formula:
$\text{CFR} = \text{SF} \times \left(1 – \frac{\text{SQ}}{100}\right)$
Variables
Variable  Description 

CFR  Condensate Flow Rate (pounds per hour) 
SF  Steam Flow (pounds per hour) 
SQ  Steam Quality (percentage) 
Calculation Example:
Inputs:

 Steam Flow (SF) = 1000 lbs/hr
 Steam Quality (SQ) = 90%
Calculation Steps:
1: Subtract the steam quality from 100.
$100 – 90 = 10$
2: Convert the result to a decimal.
$\frac{10}{100} = 0.1$
3: Multiply the steam flow by this decimal.
$1000 \times 0.1 = 100$
4. Result: The condensate flow rate is 100 lbs/hr.
Calculator Input Examples
1. Basic Calculator
Input/Steps  Values 

Input: Steam Flow (SF)  1000 lbs/hr 
Input: Steam Quality (SQ)  90% 
Step 1  Calculate $1 – \frac{SQ}{100}$ 
Calculation  $1 – \frac{90}{100} = 0.1$

Step 2  Multiply SF by the result 
Calculation  $1000 \times 0.1 = 100$

Result: CFR  100 lbs/hr 
2. Advanced Calculator
Input/Steps  Values 

Input: Steam Flow (SF)  1500 lbs/hr 
Input: Steam Quality (SQ)  85% 
Step 1  Calculate $1 – \frac{SQ}{100}$ 
Calculation  $1 – \frac{85}{100} = 0.15$$1$ 
Step 2  Multiply SF by the result 
Calculation  $1500 \times 0.15 = 225$ 
Result: CFR  225 lbs/hr 
FAQs
What is steam quality?
Steam quality is the percent of steam that is vapor. It shows how dry the steam is.
Why is condensate flow rate important?
It helps monitor, maintain efficiency, and ensure safety in the steam system.
Can I calculate CFR without steam quality?
No, you need both steam flow and steam quality to calculate the condensate flow rate.
