1. What is a Saturated Water Pressure Calculator?

Definition: This calculator estimates the saturated vapor pressure of water based on temperature using steam table data.

Purpose: It helps engineers, scientists, and students determine the equilibrium pressure of water vapor at a given temperature.

2. How Does the Calculator Work?

The calculator uses the relationship:

Where:

• \( P \) — Saturated pressure (Pascals)
• \( T \) — Temperature (°C)
• \( f \) — Function derived from steam tables

Explanation: The calculation uses empirical data from steam tables to determine the pressure at which water and vapor coexist in equilibrium.

3. Importance of Saturated Pressure Calculation

Details: Accurate pressure-temperature relationships are crucial for HVAC design, power plant operation, chemical processes, and weather prediction.

4. Using the Calculator

Tips: Enter the temperature in °C. The calculator will return the corresponding saturated vapor pressure in Pascals.

5. Frequently Asked Questions (FAQ)

Q1: What is saturated vapor pressure?
A: It's the pressure at which liquid water and water vapor are in equilibrium at a given temperature.

Q2: How accurate is this calculator?
A: This uses standard steam table data and provides results accurate for most engineering applications.

Q3: What's the temperature range validity?
A: The calculation is valid for temperatures between 0°C and 374°C (the critical point of water).

Q4: Why use Pascals as the pressure unit?
A: Pascals are the SI unit for pressure, though results can be converted to other units as needed.

Q5: How does pressure change with temperature?
A: Saturated pressure increases exponentially with temperature according to the Clausius-Clapeyron relation.
