Question
Chapter 2, Problem 2.21P
Interpretation Introduction
Interpretation:
The amount of force required to lift the block free of the bottom is to be determined along with the amount of force that is required to maintain this block in this position.
Concept Introduction:
The force
acting on a surface due to a fluid above it is defined as:
Here,
The force that leads any object to float when immersed partially or fully in a fluid is known as buoyancy or buoyant force. It is the result of the pressure differences that acts on the opposite sides of that object when immersed in the fluid which is static.

Suppression of the side reactions isachieved by excess glycerol, so the liquid product contains 3% (w/w) unreacted glycerol.2a. Draw a process diagram.
