Separating Calorimeter and Dryness Fraction Calculation
What is a Separating Calorimeter?
A separating calorimeter is a device used to determine the dryness fraction of steam. It is used to separate the moisture content from steam.
How does a Separating Calorimeter work?
In a separating calorimeter, the steam is passed through a coil, which is surrounded by a water jacket. The steam, on passing through the coil, heats the water in the jacket. The temperature rise of the water in the jacket is measured by a thermometer.
Dryness Fraction Calculation
To calculate the dryness fraction of steam, the following formula can be used:
Dryness fraction = (mass of dry steam/mass of steam) x 100%
In this case, the mass of steam collected is 4.5kg. The mass of moisture collected is 0.5kg. Therefore, the mass of dry steam can be calculated as follows:
Mass of dry steam = mass of steam - mass of moisture
Mass of dry steam = 4.5kg - 0.5kg
Mass of dry steam = 4kg
Using the formula above, the dryness fraction can be calculated as follows:
Dryness fraction = (mass of dry steam/mass of steam) x 100%
Dryness fraction = (4kg/4.5kg) x 100%
Dryness fraction = 88.9%
Therefore, the dryness fraction of the steam is 88.9%.
