Given: For Oxygen
P=100 kPa (abs)(Pressure)
T=250C=25+273=298K(Temperature)
R=260J/kg.K(Ideal gas constant)
k=1.4 (Adiabatic constant)
To find:
c(Speed of sound)
For Oxygen at the given temperature and pressure, we know that the sound in oxygen is given by
c=√kPρ
But, By Ideal gas equation
PV=mRT
Pρ=RT
Hence, …
