What type of steam is produced when steam is at 100 psi and 400 degrees F?

When steam is at 100 psi and 400 degrees F, it is classified as superheated steam. Superheated steam is defined as steam that is heated beyond its saturation point at a given pressure. At 100 psi, the saturation temperature is approximately 338 degrees F. Since the steam in this scenario is at 400 degrees F, it exceeds the saturation temperature, indicating that it is superheated.

Superheated steam has several advantages, such as increased energy content and the ability to transfer heat more efficiently, which makes it essential for various industrial applications. This high temperature allows superheated steam to do more work in turbine engines compared to saturated steam, which is critical for effective energy conversion processes.
