BTU Formula:
From: | To: |
Definition: This calculator converts the mass of steam to British Thermal Units (BTU) using the latent heat of vaporization.
Purpose: It helps engineers, HVAC professionals, and energy specialists calculate the energy content in steam for heating systems and power generation.
The calculator uses the formula:
Where:
Explanation: The mass of steam is multiplied by the latent heat value to determine the total energy content.
Details: Accurate BTU calculations are essential for designing heating systems, sizing boilers, and calculating energy efficiency in steam systems.
Tips: Enter the mass of steam in pounds and the latent heat value (default 970 BTU/lb for water). All values must be > 0.
Q1: Why is the latent heat value 970 BTU/lb?
A: This is the approximate latent heat of vaporization for water at atmospheric pressure. It varies slightly with temperature and pressure.
Q2: Can I use this for other fluids besides water?
A: No, this calculator is specifically for water/steam. Other fluids have different latent heat values.
Q3: Does this calculate sensible heat or latent heat?
A: This calculates the latent heat component only. For complete energy calculations, sensible heat should also be considered.
Q4: How accurate is this calculation?
A: It provides a good estimate for most applications, but for precise engineering calculations, pressure and temperature should be considered.
Q5: What's the difference between BTU and BTU/hr?
A: BTU measures energy, while BTU/hr measures power (energy per unit time). This calculator gives total energy in BTU.
