3. An unknown gas moving at a constant speed of 164 m/s enters a tube of constant cross sectional area at a rate of 3.00kg/s. Assuming the critical pressure and temperature are 767 kPa and 140oC respectively for a given static condition at the entrance to the tube. Assuming the ratio of specific heat and gas constant of the unknown gas to be 1.289 and 0.1889 kJ/kg K respectively. Determine a) the static pressure, temperature and density at the entrance to the tube b) stagnation temperature and pressure c) the Mach number of the gas at the entrance to the tube d) the cross sectional area of the tube e) the critical speed f) determine the unknown gas?

3. An unknown gas moving at a constant speed of 164 m/s enters a tube of constant cross
sectional area at a rate of 3.00kg/s. Assuming the critical pressure and temperature are 767
kPa and 140oC respectively for a given static condition at the entrance to the tube. Assuming
the ratio of specific heat and gas constant of the unknown gas to be 1.289 and 0.1889 kJ/kg K
respectively.
Determine
a) the static pressure, temperature and density at the entrance to the tube
b) stagnation temperature and pressure
c) the Mach number of the gas at the entrance to the tube
d) the cross sectional area of the tube
e) the critical speed
f) determine the unknown gas?
