A static thrust stand as sketched In the figure snown is used for testing a Jet engine. The following conditions are known for a typical test: the fuel enters at a fiow rate of S5 kg/s vith approximate zero velocity. Intake air velocity is 215 m/s and exhaust gas velocity is 500 m/s; intake cross-sectional area is 1.2 m^2; intake static gauge pressure -30 kPa; ntake air density is 0.9 kg/m^3 and exhaust static temperature 800 K; exhaust static pressure 0 kPa. If the atmospheric pressure is 100 kPa, the constant for air and gas is R= 287 (kg. K). Control volume Fuel inlet Patrm P1 U2 Section (2) Section (1)
