Equilibrium of Air & Steam Mixtures Model TH 176

– Two different ways to determine the vapour content. Sci-tech Equilibrium of Air & Steam Mixtures Model TH 176 uses water as working medium.

Item Description

The vapour content x is a dimensionless ratio between 0 and 1. It is defined by the ratio of mass of vapour and total mass. The total mass is calculated from the sum of fluid mass and vapour mass. If the vapour content is x=0, the evaporation medium is completely liquid, x=1 means dry saturated vapour, a value in between means wet vapour with a variable liquid content. Separating and throttling calorimeters are used to determine the vapour content. In practice, devices to determine the vapour content are used in steam power plants, downstream of steam turbines or at steam boilers upstream of the super-heater.
