4) The head (h) delivered by a centrifugal pump depends on the volume flow rate, (Q) angular speed (Ⓡ), impeller diameter (D), and fluid viscosity (μ) and density (p). a) Determine the dimensionless groups that characterize pump head. b) The power (Pw) required by a pump depends on the same variables: volume flow rate, (Q) angular speed (), impeller diameter (D), and fluid viscosity (μ) and density (p). Determine the dimensionless groups that characterize power required by a pump. c) If you correctly formed your dimensionless groups, in both cases you should obtain a dimensionless group of the form poD²/μ. What does this dimensionless group correspond to? 4) The head (h) delivered by a centrifugal pump depends on the volume flow rate, (Q) angular speed (Ⓡ), impeller diameter (D), and fluid viscosity (μ) and density (p). a) Determine the dimensionless groups that characterize pump head. b) The power (Pw) required by a pump depends on the same variables: volume flow rate, (Q) angular speed (o), impeller diameter (D), and fluid viscosity (μ) and density (p).
