The article proposes the theoretical framework of ventilation processes emerging and going on in the stages of TPP steam turbines during the operating regimes with small-quantity volumetric flow rates in the low-pressure cylinder. The basic theory includes new physicomathematical models for estimating the ventilating capacity losses and ventilation heatings-up of the steam and the air... https://www.roneverhart.com/DigiWeigh-Notebook-Digital-Pocket-Scale-1000g-x-0-1g/
