Chapter 1: Problem 52

Poise is the unit of (a) viscosity (b) velocity (c) force (d) time

Short Answer

Expert verified
The unit of poise is associated with viscosity. Thus, the correct answer is (a) viscosity.

Step by step solution

01

Understand the Units of Each Given Quantity

To determine which quantity is measured in the unit of poise, let's first recall the units of each of the given quantities: (a) Viscosity: its SI unit is Pascal-seconds (Pa·s), but other units are also used, such as the cgs (centimeter-gram-second) unit, which is poise (P). (b) Velocity: its SI unit is meters per second (m/s). (c) Force: its SI unit is Newton (N). (d) Time: its SI unit is the second (s).
02

Identify the Quantity with the Unit Poise

From our understanding of the units of each given quantity, we can conclude that the unit of poise is associated with viscosity. Therefore, the correct answer is: (a) viscosity
