Fluid Mechanics

Step 1: Define the fluid behaviors.
A. Shear-thinning (Pseudoplastic): Viscosity decreases as shear rate increases. Shaking or stirring makes it flow more easily. Tomato ketchup is a classic example. So, A-I.
B. Newtonian: Viscosity is constant regardless of shear rate. Milk (and water) behaves approximately as a Newtonian fluid. So, B-II.
C. Shear-thickening (Dilatant): Viscosity increases as shear rate increases. It becomes thicker when stirred or hit. A concentrated corn starch solution is the prime example. So, C-IV.
D. Bingham plastic: Behaves as a rigid solid at low stress but flows like a viscous fluid at high stress. It has a "yield stress". Whipped cream, toothpaste, and mayonnaise are examples. So, D-III.
The correct set of matches is A-I, B-II, C-IV, D-III.

Step 1: Identify the constant component. In a drying process, water is removed, but the mass of the solid material remains constant.

Step 2: Calculate the initial mass of solids.
Initial total weight = 100 kg
Initial moisture content = 85%
Initial solids content = 100% - 85% = 15%
Mass of solids = 100 kg 0.15 = 15 kg.

Step 3: Use the constant mass of solids to find the final total weight.
Final moisture content = 10%
Final solids content = 100% - 10% = 90%
The 15 kg of solids now constitutes 90% of the final product's weight. Final Weight 0.90 = 15 kg

Step 4: Solve for the Final Weight.
Final Weight = 15 kg / 0.90 = 16.666... kg.
Rounding to two decimal places gives 16.67 kg or 16.66 kg.

Step 1: Understand viscosity. Viscosity is a measure of a fluid's resistance to flow. A higher value means the fluid is "thicker".

Step 2: Rank the substances in LIST-I by their expected viscosity, from lowest to highest. Air (a gas) will have the lowest viscosity. Water is a common reference fluid, much more viscous than air. Olive Oil is noticeably more viscous than water. Liquid Honey is extremely viscous and flows very slowly. The correct order of increasing viscosity is Air \textless Water \textless Olive Oil \textless Liquid Honey.

Step 3: Rank the viscosity values in LIST-II from lowest to highest. \textless \textless \textless .

Step 4: Match the ranked lists.
A. Air \textrightarrow I. Pa.s
B. Water \textrightarrow II. Pa.s (The viscosity of water is approximately 1 mPa.s or 0.001 Pa.s)
C. Olive Oil \textrightarrow III. Pa.s
D. Liquid Honey \textrightarrow IV. Pa.s
The correct set of matches is A-I, B-II, C-III, D-IV.
