Why is low-pressure steam more efficient?
Low-pressure steam is more efficient for a few reasons: 1. It takes less energy to make low-pressure steam because it’s at a lower temperature and pressure. 2. Low-pressure steam can transfer more heat per unit of steam because it has a higher latent heat of vaporization. 3. These systems often lose less heat because the temperature difference between the steam and the surroundings is smaller.
How to find steam temperature from pressure?
To find steam temperature from pressure, use the steam tables or the Clausius-Clapeyron equation. The steam tables give the temperature for a certain pressure. The equation lets you calculate the temperature from the pressure.
