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.

Correct Answer: False, True
The viscosity of these fluids decreases as the shear rate increases. Blood, tomato puree are the examples of the pseudo plastic fluids. Another example is that, suspension of the corn starch in water with 1:1 concentration. Then this corn starch behaves like water when no force is applied. Still it is solidified as force is applied.

Heinz produces tomato puree by boiling tomato juice. Tomato puree has 20% water whereas tomato juice has 90% water.How many litres of tomato puree will be obtained from 20 litres of tomato juice ?

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.

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: Considering the equation, μ_a= τ/γ = Kγ(n-1) , for pseudo plastic fluids, n<1 and they’re called Shear thinning liquids and dilatant fluids are called Shear thickening liquids as n>1. Statement 2: Cooked starch solution is a Shear thinning liquid and dairy cream is a Shear thickening liquid.

With increase in the shear rate, the apparent viscosity of pseudoplastic fluids

For turbulent flow (NRe > 2100) of low viscosity fluid (μ > 20cp) in steel pipes, the optimum inside pipe diameter is given by (where, Q = fluid flow rate, ft3/sec.ρ = fluid density, lb/ft3.μ = fluid viscosity, centipoise Di = optimum inside pipe diameter, inches)

Shear stress versus shear rate behavior of four different types of fluids (I, II, III and IV) are shown in the figure below.

Which one of the following options is correct?

Which of the following statements are true/false?
1. A minimum rate of wages for the time spent by employees for the production of output is minimum time rate.
2. Minimum piece rate is the rate based on the quantity of the output employees have produced.
3. The guaranteed time rate is a minimum rate of remuneration to apply in the case of employees employed on piece work for the purpose of securing to such employees a minimum rate of wages on a time work basis.
4. A minimum rate of remuneration to apply in the case of employees employed on piece work for the purpose of securing to such employees a minimum rate of wages on a time work basis is overtime rate.

Are these statements about the Fluid mechanics true? Statement 1: Fluid mechanics is a branch in chemistry that involves study of fluids. Statement 2: Fluid mechanics can be divided into 2 major categories.

As per Newton's law of viscosity, the shear stress for a given rate of angular deformation of fluid is proportional to (where, $$\mu $$ = fluid viscosity)
