Ideal Pressure for Steam Generation and Distribution

Secondly, reducing pressure at the point of usage also ensures that steam delivered has a higher dryness fraction. Consider steam traveling at a pressure of 9 bar g having dryness fraction of 0.95. The pressure of steam is now reduced to 3 bar g. This pressure reduction leads to an increase in dryness fraction that can be calculated using the
