DESIGN PROBLEM: Design an axial fan with following specification for air handling unit. Q = [0.2×R + 8] m3/s H = [10 + 0.1×R] m Where, R is your class roll number {1, 2, 3, ….. , 20} Rotational Speed = 1200 RPM Assume any missing data. Objectives: Calculate the geometry of axial fan (size of nozzle, no of blades, aspect ratio and solidity). Use CAD software to show the design drawing. Draw a velocity triangle of the fan. Also draw performance chart (H vs Q) State all the assumptions made.
