Air is pumped through the stationary duct A with a velocity of 50 ft/sec and exhausted through an experimental nozzle section BC. The average static pressure across section B is 150 lb/in.² gage, and the specific weight of air at this pressure and at the temperature prevailing is 0.840 lb/ft³. The average static pressure across the exit section C is measured to be 2 lb/in.² gage, and the corresponding specific weight of air is 0.0760 lb/ft³. Calculate the force T exerted on the nozzle flange at B by the bolts and the gasket to hold the nozzle in place.
