Question

At the inlet and exhaust of a turbine, the absolute steam pressures are 6000 kN/m² and 4.0 cm Hg, respectively. The barometric pressure is 75 cm Hg. Calculate the gauge pressure for the entering steam and the vacuum gauge pressure for the exhaust steam.

Answer 1

$p_1'=p_1-p_0,$

$p_2'=p_0-p_2,$

$p_1'=5899~\frac{kN}{m^2},$

$p_2'=71~cm~Hg.$
