The performance data of Problem 10.57 are for a 36-in.-diameter fan wheel. The fan also is manufactured with 42-, 48-, 54-, and 60-in.-diameter wheels. Pick a standard fan to deliver 600 ft3/s against a 1-in. water static pressure rise. Determine the required fan speed and input power required.
Performance data for a centrifugal fan of 3-ft diameter tested at 750 rpm are
Plot the performance data versus volume flow rate. Calculate static efficiency, and show the curve on the plot. Find the best efficiency point, and specify the fan rating at this point.

- A sign ABCD is constructed from 5 mm thick plate steel (density p =8000 kg/m³) with the geometry shown in the figure. The sign is connected to the wall by a pin at A and also supported by member DE. Support member DE is also constructed from 5 mm thick plate steel and is connected by pins at B and E respectively. Determine the reaction forces at A and E. Enter your answers in Cartesian components. The weights of both the sign D and member DE should be accounted for in the calculation.
