a horizontal diffuser operating at steady state is used to slow the flow of co2. the inlet volumetric flow rate is 10 m3 /s, and the inlet temperature and pressure are 600 k and 200 kpa, respectively. the exit area to inlet area ratio is 5. specific heat transfer from the diffuser was determined to be 100 kj/kg. the exit temperature and pressure are 580 k and 300 kpa, respectively. determine the volumetric flow rate and the velocity at the exit
