Properties of Saturated Steam
This saturated steam table reveals critical thermodynamic trends: pressure escalates exponentially with temperature (from 0.6 kPa at 0°C to 22,064 kPa at the critical point), while steam density surges 650-fold as it approaches the critical phase. Notably, latent heat of vaporization declines steadily with rising temperatures, and steam enthalpy peaks at mid-range temperatures (~240°C) before dropping. Engineers rely on this data to design boilers and HVAC systems (using pressure-temperature correlations), optimize turbine performance (via enthalpy changes), and ensure process safety (through density-pressure analysis). The values adhere to IAPWS-97 standards, making them indispensable for energy, mechanical, and chemical engineering applications
