Answer:
Vw = 2.80907 E-3 m³/Kg
Explanation:
specific volume is the inverse of density:
⇒ Vw = 1 / ρ
∴ water at:
⇒ P = 1400 KPa * ( 1000 Pa / KPa ) = 1400000 Pa
⇒ T = 200°C = 473 K
Water at these conditions is found as saturated steam, specific volume would be:
⇒ Vw = R*T / P
∴ R = 8.3144 Pa.m³/ Kg.K
⇒ Vw = (( 8.3144 ) * ( 473)) / 1400000
⇒ Vw = 2.80907 E-3 m³/Kg
