HIGH-TEMPERATURE STEAM TENSION Description and Specifications for Lab Tenders
HIGH-TEMPERATURE STEAM TENSION.
HIGH-TEMPERATURE STEAM TENSION Water is heated inside a closed chamber under pressure;
water will vaporize when the pressure inside the chamber
corresponds to the steam pressure at that temperature.
Heat of vaporization is determined at various temperatures
from the measure of steam tension versus temperature.
