Note:

This formula calculates the steam consumption required to compensate for heat losses in a tank.

Where:

• ṁs = Mean steam flowrate required to compensate for heat loss (kg/s).
• Q = Total heat loss from the system, calculated as:
  • Q_sides: Heat lost from tank sides (kW).
  • Q_surface: Heat lost from the surface (kW).
• 2256.7 = Enthalpy of evaporation of steam at atmospheric pressure (kJ/kg).

Where Can This Formula Be Used?

This formula is widely used in industrial applications , particularly in Safety and Fire Protection Systems , including:

• Industrial boiler operations – Ensuring steam flow is adequate for maintaining process temperatures.
• Fire suppression systems – Using steam to prevent overheating of flammable tanks.
• Heat recovery systems – Estimating steam requirements for insulation and efficiency improvements.
• Temperature-controlled storage – Maintaining the correct temperature in tanks storing volatile substances.

Input Constraints

• Q (Heat Loss) must be a positive numeric value (kW).
• Mandatory Input: If Q is 0 or negative , an error should be displayed.
• The formula assumes atmospheric pressure conditions . If pressure varies, adjustments are needed.
