How to Use

To utilize the deaerator vent rate calculator, simply input the required parameters such as the deaerator pressure, feedwater temperature, and vent rate coefficient. After providing these inputs, click the “Calculate” button to obtain the vent rate value.


The formula used in the deaerator vent rate calculation is as follows:


  • C represents the vent rate coefficient
  • P denotes the deaerator pressure
  • T signifies the feedwater temperature

Example Solve

Suppose we have the following values:

  • Vent rate coefficient (C): 0.1
  • Deaerator pressure (P): 15 psig
  • Feedwater temperature (T): 210°F

Using the provided formula, the calculation would be as follows:

Upon solving, we get the vent rate as 0.213 lb/h.


Q: What is the significance of the vent rate coefficient?
A: The vent rate coefficient represents the efficiency of the deaerator in removing dissolved gases from the feedwater.

Q: Can this calculator be used for different units of pressure and temperature?
A: Yes, as long as the units are consistent, the calculator can handle various units of pressure and temperature.

Q: Is the provided formula universally applicable?
A: The formula is suitable for standard conditions; however, adjustments may be necessary for specific scenarios or non-standard conditions.


In conclusion, the deaerator vent rate calculator serves as a valuable tool for engineers and technicians involved in steam system design and operation.
