“In Rheopectic fluid apparent viscosity decreases with time the fluid”?(a) True(b) FalseThe question was asked in an interview for job.My question is from Non Newtonian Fluids topic in portion Fluid Flow and Mixing of Bioprocess Engineering

Answer»

The correct choice is (b) False

Easy explanation: When a shear force is EXERTED on some fluids, the apparent VISCOSITY EITHER increases or decreases with duration of the force. If apparent viscosity increases with time, the fluid is SAID to be rheopectic; rheopectic fluids are relatively rare in OCCURRENCE. If apparent viscosity decreases with time the fluid is thixotropic.
