How does density affect fluid flow?

see below


density (#rho#) that is the ratio between mass and volume is present in Reynold's number
#Re= (rho xx d xx v)/ (mu)#
and its increasing, increase the possibility to have a turbolent flow (when Re > 4000)
To move the fluid you have to give electric power according to the relation:
#N= (F xx H)/(eta)#
where N is the Power
H is the prevalence
#eta# is the efficiency of the pump
and F is the mass flow of the fluid: mass flow = volum flow x density
