To determine The average velocity at the exit of the turbine. Explanation Given: Mass flow rate of air ( m ˙ ) is 40 kg/s . The absolute pressure ( p ) is 750 kPa The temperatue of the air ( T a ) is 120 ° C . The diameter of the exit ( d ) is 0.3 m . Calculation: Calculate the total temperature T t . T t = T + T a T t = 273 K + 120 ° C = 393 K Here, static standard temperature is T . Refer Appendix A, “Physical properties of gases at standard atmospheric pressure 101.3 kPa” in the textbook, the gas constant for the air ( R ) is 286.9 J / kg ⋅ K . Calculate the density of air ρ . p = ρ R T t ( 750 kPa × 10 3 ) N/m 2 = ρ × 286
