Meriam, Kraige & Bolton — Kinetics of Systems of Particles: Problem 4_43

4/43 Air is pumped through the stationary duct \(A\) with a velocity of \(50 \text{ ft/sec}\) and exhausted through an experimental nozzle section \(BC\). The average static pressure across section \(B\) is \(150 \text{ lb/in.}^2 \text{ gage}\), and the specific weight of air at this pressure and at the temperature prevailing is \(0.840 \text{ lb/ft}^3\). The average static pressure across the exit section \(C\) is measured to be \(2 \text{ lb/in.}^2 \text{ gage}\), and the corresponding specific weight of air is \(0.0760 \text{ lb/ft}^3\). Calculate the force \(T\) exerted on the nozzle flange at \(B\) by the bolts and the gasket to hold the nozzle in place.
