Statement 1: For non-Newtonian fluids, another term called apparent viscosity is used as their viscosity changes with the change in the shear rate. Statement 2: For non-Newtonian fluids, between the transition region, the power number for non-Newtonian fluids is slightly higher than that for Newtonian fluids.
Name the type of impeller used for agitation of low viscosity fluids, on high speeds?
Statement 1: Blood is a _____ Statement 2: Thixotropic fluids are fluids whose viscosity decreases when subjected to shear stress initially but eventually with time, the viscosity increases.
Statement 1: In μ_a= τ/γ = Kγ(n-1) , n = consistency index and K is the flow behaviour index. Statement 2: n= 1 for Newtonian fluids, n<1 for dilatant fluids and n>1 for pseudo plastic fluids.
Correct viscosity of furnace oil at the burner tip for proper atomisation is about 25 centistokes. To reduce the viscosity of high viscosity furnace oil (250 centistokes) to the correct atomisation viscosity (i.e. 25 cst), it should be preheated to about____°C.
The mixing vat in a factory receives liquid ingredients through six separate value--- labeled R.S.T.U,Y and Z -- each of which has exactly two settings: open and closed.The mixing vat operator must ensure that each valve is set open or closed according to the following conditions: If T is open, both S and Z must be closed, R and Z cannot both be closed at the same time; If Y is closed, Z must also be closed;S and U cannot both be open at the same time. Which of the following, if given to the mixing vat operator as an instruction, would not determine the setting of any other valve ?
The impeller type electric fuel pump consists of a pump casing, a DC motor, an impeller, a relief valve, and a check valve.
Height of liquid in agitation tank is normally maintained equal to the tank diameter. However, if the tank is too tall and a large liquid hold up is desired, then two or more impellers mounted on the same shaft may be used. The clearance between the tank bottom and the bottom most impeller should be about (where, D = impeller diameter)
___________ is valid for any fluid (liquid or gas); it is especially crucial to fluids moving at a high velocity. Its principle is the basis of venturi scrubbers, thermo—compressors, aspirators, and other devices where fluids are moving at high velocities.
Are these statements about the pseudoplastic fluids true? Statement 1:The viscosity of these fluids decreases as the shear rate decreases. Statement 2: Tomato puree is an example of pseudoplastic fluid.
