Include program flowchart (pseudo code) and C++ source code (Codeblocks is recomended) in the report

You are a Mechanical design engineer in the hydraulics section of a company. You are tasked with specifying the duty point of stable centrifugal blowers that are to be installed as ventilators in buildings. The key design variable that affects the duty point is the design blade angle for impellers of centrifugal blowers with given dimensions The blowers discharge air at atmospheric pressure (air density 0.075 lb/ft?) from rooms in the buildings into the atmosphere at given flow rates (ft/min). The air is discharged through 5 x 6 inch rectangular openings. The intemal and extemal diameters of the impellers are 7 and 8.5 inches respectively and the blades are of constant width of 5 inches. The blower speed is to be 750 RPM. (Assume the blowers have no inlet guide vanes). (a) Write a simple program in C++ language that gives the duty point (flowrate Q in ft/min, and static pressure change across the blades in inches of H20). The inputs to the program must include; design blade angle, external diameter of impeller, blade width and speed of blower. (20 Marks) (b) When run your program should print the message "Blade angle error" instead of the duty point in (a) if the blade angle entered would cause instability during blower operation. (5 Marks) (c) Test your program for design blade angle 24.6 and print the duty point for this angle. (5 Marks) You are a Mechanical design engineer in the hydraulics section of a company.
