Mechanical Engineering

Air at 50 ° C with 1.7 bar gauge pressure enters thecylindrical bearing system, the diameter of which is below, andstanding in an upright position, with an average flow rate of 2.6 m/ s for drying purposes. In the fluid state, the porosity value ofthe bed is desired to be 0.61 m and its height 0.53 m. Inside thebed are fresh kidney beans with a diameter of 8 mm.
a). When the air enters the bed, is the inlet speed of the airsufficient for the bed to be in a fluid form as desired above, oris it necessary to adjust the air speed in accordance with thedesired conditions?
b). Find the drag force that acts on a single kidney bean while thebearing is fluid.
c) What is the absolute pressure value of the air when leaving thefluidized bed?

You can get the density of kidney bean grains 1120 kg/ m.
The diameter of the bed is 18 cm
