Nitrogen, modeled as an ideal gas, flows at a rate of

`7k(g)/(s)`

through a well-insulated horizontal nozzle operating at steady state. The nitrogen enters the nozzle with a velocity of

`20(m)/(s)`

at

`340K,400kPa`

and exits the nozzle at 100 kPa To achieve an exit velocity of

`478.8(m)/(s)`

, determine: (a) the exit temperature, in K . (b) the exit area, in

`m^(2)`

. Part A To achieve an exit velocity of

`478.8(m)/(s)`

, determine the exit temperature, in K .

`T_(2)=`

K Part B To achieve an exit velocity of

`478.8(m)/(s)`

, determine the exit area, in

`m^(2)`

.

`A_(2)=`

`m^(2)`
