Condensate Flow Rate Calculator

How to calculate the condensate flow rate? For correct calculation use our Condensate Flow Rate checker tool. Simply enter the steam flow and steam quality into the calculator to find out condensate flow rate.

Enter the required values to calculate the condensate flow rate. In advanced mode, you can calculate the enhanced condensate flow rate considering steam quality and pressure drop.

Enter the steam flow in pounds per hour (lbs/hr). This is the volume of steam flowing per hour. Enter the steam quality as a percentage (%). Steam quality is the percentage of steam in the steam-water mixture. Enter the condensate flow rate in pounds per hour (lbs/hr). This is the volume of water returning after the steam condenses.

Enter the total steam flow in pounds per hour (lbs/hr). This is the volume of steam flowing per hour. Enter the average steam quality as a percentage (%). Steam quality is the percentage of steam in the steam-water mixture. Enter the pressure drop in pounds per square inch (psi). This refers to the drop in pressure as the steam travels through the system. The enhanced condensate flow rate in pounds per hour (lbs/hr) will be displayed here.

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:

More Calculators

 $\text{CFR} = \text{SF} \times \left(1 - \frac{\text{SQ}}{100}\right)$

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	$1 – \frac{85}{100} = 0.$
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.
