Consider a control volume around the pump through which an incompressible fluid of density p flows at a volume flow rate of Q. Since the flow enters at one point and leaves at another point the volume flow rate Q can be independently adjusted by means of a throttle valve. The discharge Q of a pump is given by Q= f (N, D, g, H, µ, p);

Please the correct option
Transcribed Image Text:leaves at another point the volume flow rate
Q can be independently adjusted by means
of a throttle valve. The discharge Q of a
pump is given by
Q= f (N, D, g, H, H, );
Where H is the head, D is the diameter of
impeller, g is the acceleration due to gravity,
pis the density of fluid, N is the revolution,
and u is the viscosity of fluid. Taking N, D,
and p as repeating variables, determine the
appropriate dimensionless parameters
Select one:
O a. QIND = f(gH(N²D²), µ/(ND° p))
b.
Q/(ND) = f(gH?)/(N²D?), µ/NDp)
c.
Q/(ND²) = f(gH/(N²D³), µ/(ND²P))
O d.
Q(ND) = f(gH(N²D³), µ/(ND²P})
