Step 1: Understanding vertical screw mixers.
- Vertical screw mixers are designed for powdery and granular dry solids, ensuring homogeneous mixing.
Step 2: Explanation of incorrect options.
- (A) High viscous liquids: Require agitated tank mixers.
- (B) Low viscous liquids: Best mixed using paddle or propeller mixers.
- (C) Moderate viscous fluids: Better handled by turbine mixers.
Step 3: Selecting the correct option. Since vertical screw mixers are best for dry solids, the correct answer is (D) Dry solids.
If A + B means A is the mother of B; A - B means A is the brother of B; A % B means A is the father of B, and A \(\times\) B means A is the sister of B, which of the following shows that P is the maternal uncle of Q?
