Note:

This formula calculates the steam condensing rate for air heating equipment.
It helps engineers determine the rate of steam condensation necessary to heat air efficiently.
Proper calculation ensures energy efficiency and prevents excessive steam consumption.

Understanding Parameters:

• Steam Condensation Rate (ṁₛ) (kg/h): The rate at which steam condenses while heating air.
• Volumetric Flowrate of Air (V̇) (m³/s): The amount of air being heated per second.
• Air Temperature Rise (ΔT) (°C): The increase in air temperature due to heating.
• Specific Heat of Air (cₚ) (kJ/m³°C): The energy required to raise the temperature of air by 1°C per cubic meter.
• Enthalpy of Evaporation (h_fg) (kJ/kg): The energy required to convert water into steam.

Why 3,600?

The constant 3,600 is used in the formula to convert the result into kg/h. Here's why:

• Volumetric flowrate (V̇) is in m³/s, and temperature rise (ΔT) is in °C.
• The enthalpy of evaporation (h_fg) is given in kJ/kg.
• Since 1 hour = 3600 seconds, this factor converts the result from per second to per hour.

Without this factor, the output would be in kg/s, requiring an additional step for conversion.

Input Value Restrictions:

• Volumetric Flowrate of Air (V̇): Must be positive; air must have a measurable flowrate.
• Air Temperature Rise (ΔT): Cannot be negative; heating increases temperature.
• Specific Heat of Air (cₚ): Always positive, as it represents energy absorbed per unit volume.
• Enthalpy of Evaporation (h_fg): Always positive, as it represents the energy needed to produce steam.

Applications:

• HVAC Systems: Helps optimize air heating processes in buildings.
• Industrial Heating Equipment: Ensures efficient steam-based heating in factories.
• Power Plants: Supports optimal steam usage in turbines and boilers.
• Food and Beverage Industry: Helps maintain controlled heating for food processing.
• Pharmaceutical and Chemical Industries: Ensures temperature control in steam-reliant production.

Conclusion: This tool helps industries optimize steam usage, minimize energy waste, and maintain operational efficiency. By inputting accurate values, users can ensure a balanced heating process while reducing unnecessary steam consumption.
