Fluid Flow MCQs

A rheopectic fluid is one in which the viscosity

A fluid in which the viscosity increases with increasing stirrer speed and mixing time can be called as

The medium will have the highest viscosity (considering that the cells do not secrete gums) with the presence of

A Newtonian fluid is one in which the viscosity

Which pattern of mixing is preferred in stirred tank reactors during the culture of aerobic microorganisms?

Animal cell cultures do not have much effect on shear forces because

The viscosity of the culture fluid is classified as both pseudoplastic and thixotropic which indicates that the viscosity

Pluronic F68 is added to cell culture media as

A stirred tank reactor containing a fluid with a density of 2.5 g.ml-1 and viscosity of 0.002 kg m-1s-1 is mixed at 120 rpm. If the fluid is mixed with an impeller having diameter 50 cm, then the Reynolds number of the liquid in the reactor is
