Air at $$ 20^\circ C $$ and $$ 10^5 $$ Pa enters the bottom of an $$ 85^\circ $$ conical flow meter duct at a mass flow rate of 0.3 kg/s, as shown in the figure. It supports the centered conical body by steady annular flow around the cone and exits at the same velocity as it enters. Estimate the weight of the body in Newtons
