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 centrifugal fan with radial vanes delivers 4 m3/s of atmospheric air at 30°C when spinning at 2400 rpm. The total pressure rise across the fan is equivalent to 120 cm of water. If air enters the rotor radially, calculate the specific speed and the fluid angle at the exit of the fan.arrow_forwardDetermine the recommended minimum speed (rpm) for a radial flow pump operating at 0.165 m3/s of water against a head of 300 marrow_forwardDetermine the non dimensional parameters that can be employed for scaling studies in centrifugal pumps.arrow_forward
- A centrifugal pump has a 41.5-in-diameter impeller. It is used to deliver water at about 12,000 gal/min. Its pump performance curve when spun at 710 RPM is shown in the figure below. If the impeller is trimmed to a new diameter of 39.5in, estimate the new head (in feet) and flow (in gal/min or GPM) if the speed is not changed.arrow_forwardA single-stage centrifugal pump has an impeller speed of 1750 rpm. If the flow rate of water is 60 gal/min, determine the expected head.

If the speed is reduced to 1200 rpm calculate the power , assuming the same efficiency.arrow_forward

The vane tips are radial at the outlet. Calculate the net head developed. Assume a value for the manometric efficiency of the pump.arrow_forward
- Consider a centrifugal pump with curved blades has blade angle at the outlet section equal to 30o, and no shock/no swirl at inlet. Construct the velocity diagrams of this blade at inlet and outlet sections.arrow_forwardUsing affinity laws, develop a pump curve and BHP curve for a 1 ½" AB pump for a 6" impeller. Use a 1750 rpm curve as the "known" characteristics and develop a theoretical curve using affinity laws for 3500 rpm based upon flow rates 0, 20, 40, 60, 80 and 90 gpm at 1750 rpm. Plot the theoretical (affinity-based) and published flow vs. head and flow vs. horsepower curves for 3500 rpm.arrow_forwardA centrifugal pump was designed for a 1940 rpm operation and a head of 63.4 m has a capacity of 201.2 l/s (lps) with a power of 135. kW. What effect will a speed reduction to 1200 rpm have on the head, capacity and power input of the pimp? What will be the changes in these variables if the impeller diameter is reduced from 332.5 mm to 275 mm while the speed is constant at 1800 rpm? Required a. For D = c, find Q2, H2 and P2 b.
