Answer 1

The terribine will have handie stoom with a quality le high moisture cortent. e implement of liquid droplet on the elite blades came erosion and is a majur source of woon Thus Steam quauity less than qon Camot be tolerated. * Correct answer (a) © CORTPtOct enquer (C) ③ (1) Heat reale (4 ) Exposion of steam from superheated occure in region to turbine mixture region. Wturbine correct answer (C) concreet onswer (6) stase - TE- Stage - (6 (6) sepertheated vapour
