Condensation Rate Formula:
| From: | To: |
The condensation rate (ṁ_cond) represents the mass flow rate of condensate formed when vapor changes phase to liquid. It quantifies how much mass is converted from vapor to liquid per unit time during the condensation process.
The calculator uses the condensation rate formula:
Where:
Explanation: The formula calculates the mass of vapor that condenses per second based on the amount of heat removed and the energy required for phase change.
Details: Accurate condensation rate calculation is crucial for designing heat exchangers, refrigeration systems, power plants, and various industrial processes involving phase change heat transfer.
Tips: Enter heat removal rate in watts (W) and latent heat of vaporization in joules per kilogram (J/kg). Both values must be positive numbers greater than zero.
Q1: What is latent heat of vaporization?
A: Latent heat of vaporization (h_fg) is the amount of energy required to change a unit mass of substance from liquid to vapor at constant temperature and pressure.
Q2: Why is condensation rate important in engineering?
A: It helps determine the capacity of condensers, design efficient heat transfer systems, and optimize energy usage in various industrial applications.
Q3: What are typical values for latent heat of vaporization?
A: For water at atmospheric pressure, h_fg is approximately 2,260,000 J/kg. Values vary for different substances and conditions.
Q4: Can this formula be used for all fluids?
A: Yes, the formula applies to any fluid, but the latent heat value must be appropriate for the specific fluid and operating conditions.
Q5: What factors affect condensation rate?
A: Surface temperature, vapor pressure, surface geometry, presence of non-condensable gases, and fluid properties all influence condensation rate.
