Chemical Engineering > GATE 2019 > Agitation
disk turbine is used to stir a liquid in a baffled tank. To design the agitator, experiments are performed in a lab-scale model with a turbine diameter of 0.05 m and a turbine impeller speed of 600 rpm. The liquid viscosity is 0.001 Pa s while the liquid density is 1000 kg/m3. The actual application has a turbine diameter of 0.5 m, an impeller speed of 600 rpm, a liquid viscosity of 0.1 Pa s and a liquid density of 1000 kg/m3. The effect of gravity is negligible. If the power required in the lab-scale model is P1 and the estimated power for the actual application is P2, then the ratio P2/P1 is
A
$10^{5}$
B
$10^{4}$
C
$10^{3}$
D
$10^{2}$

Correct : c
