Concept:
Ideal gas law: A gas which follows the ideal gas equation is known as ideal gas. Ideal gas equation is
P = ρRT
Where, P = Pressure, R = Gas constant, T = Temperature of gas
Calculation:
Given:
P = 200 bar = 200 × 105 N/m2, T = 500 K, R = 319.3 J/kgK
Using P = ρRT
200 × 105 = ρ × 319.3 × 500
ρ = 125.27 kg/m3
