The Boiling Point of Water Calculator

What is the Boiling Point of Water? Water boils at 212°F at sea level, but only at sea level. Changes in atmospheric pressure will alter the temperature at which water boils. To use this calculator you will need your current pressure and elevation. How to Calculate the Boiling Point of Water. Step 1: Find your local pressure and elevation

Heating water in a vacuum

2/2/2018 · The problem is: I want to heat water to boiling point with the least amount of energy required. I found out that if you apply vacuum into an chamber with water (room temp), the boiling point can be as low as room temperature. Now, I understand that once the chamber is pressurized the water is once again at room temp.

Boiler Feedwater Treatment (Part I): Why Water Treatment

At a pressure of 200 psig, for example, water boils at a temperature of about 388oF. At the critical pressure of 3200 psig (where water is converted to steam without change in volume), the boiling point is 704oF. As the pressure decreases, the boiling point of water decreases. Under vacuum water will boil at temperatures as low as 35oF.

Boiler (power generation)

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
