Some tools should be cleaned in water at a least 150C. How high a P is needed?

Solution

For cleaning any tool in water at 150C , we must ensure that water should remain in liquid phase.

To clean the tool at minimum pressure , 150C should be the saturation temperature.

From (Sonntag, Borgnakke and van Wylen\'s Thermodynamic steam table)

at 150C, P(saturation) = 475.9 kPa

So Pressure must me greater than 475.9 kPa.
