Consider the fan and performance data of Problem 10.84.

At Q 5 200 ft3

/s, the dynamic pressure is equal to 0.25 in.

of water. Evaluate the fan outlet area. Plot total pressure rise

and input horsepower for this fan versus volume flow rate.

Calculate the fan total efficiency, and show the curve on the plot.

Find the best efficiency point, and specify the fan rating at this

point.
