Question: q volume flow rate phi flow coefficient h head...

Question details


A centrifugal water pump is to be designed to produce Q-4.54 mmin H-21.34m and at N-870 rpm. Using an tintim value of-EL:05, φ=-mi =-w-= 0.09. slip factor of μ = 0.71 5 and to estimate Hydraulic efficiency use η,-I-_-_ where Q is in GPM & lin-2641 7GPM Deternine the geometry of the impeller: 0.8 a) The impeller tip speed U b) Impeller exit diameter d c Impeller exit width b d) β2b e) n

Q = Volume Flow Rate

Phi= Flow Coefficient

H= Head

N= Rotational Speed (rpm)

C= Absolute Velocity

U2= Impeller Tip Speed

Wm2= Relative Velocity/Work

Beta2= Blade angle with respect to tangent

f=fluid

m= meridional

2= impeller exit
