1. What is Condensate Flow Rate?

The condensate flow rate represents the mass flow rate of condensate generated from latent heat removal during phase change processes, particularly in steam systems and refrigeration cycles.

2. How Does the Calculator Work?

The calculator uses the condensate flow rate formula:

Where:

• \( Flow \) — Condensate flow rate (kg/s)
• \( Q_{latent} \) — Latent heat removal rate (W)
• \( h_{fg} \) — Latent heat of vaporization (J/kg)

Explanation: This equation calculates the mass flow rate of condensate produced when steam or vapor condenses, based on the energy removed during the phase change process.

3. Importance of Condensate Flow Calculation

Details: Accurate condensate flow rate calculation is essential for designing steam systems, sizing condensate return lines, optimizing heat exchanger performance, and ensuring efficient energy recovery in industrial processes.

4. Using the Calculator

Tips: Enter latent heat removal in watts (W) and latent heat of vaporization in joules per kilogram (J/kg). Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is latent heat of vaporization?
A: Latent heat of vaporization is the amount of energy required to change a substance from liquid to vapor at constant temperature and pressure, or vice versa.

Q2: Why is condensate flow rate important in steam systems?
A: It helps determine the capacity of condensate return systems, prevents water hammer, ensures proper steam trap sizing, and maximizes energy efficiency.

Q3: What are typical values for latent heat of vaporization?
A: For water at atmospheric pressure, h_fg is approximately 2257 kJ/kg. Values vary with pressure and temperature for different substances.

Q4: How does pressure affect the calculation?
A: Higher pressures generally decrease the latent heat of vaporization, which affects the condensate flow rate for the same heat removal.

Q5: Can this calculator be used for refrigerants?
A: Yes, the formula applies to any substance undergoing phase change, but you must use the appropriate latent heat value for the specific refrigerant and conditions.
