Question
The 11.25-in impeller option of the Taco Model 4013 FI Series centrifugal pump is used to pump water at
400 gpm at 25°C from a reservoir whose surface is 4.0 ft above the centerline of the pump inlet. The
piping system from the reservoir to the pump consists of 10.5 ft of cast iron pipe with an ID of 4.0 in and
an average inner roughness height of 0.02 in. There are several minor losses: a sharp-edged inlet (K,
0.5), three flanged smooth 90° regular elbows (K,= 0.3 each), and a fully open flanged globe valve (K, =
6.0). Determine whether there is a danger of cavitation at this flow rate or not. Discuss how you might
increase the maximum flow rate while still avoiding cavitation.
For water at 25°C, r=997kg/m’, m=8.91 x10* Pa.s and P=3.169 kPa.
