Question

PROBLEM:

An Ostwald viscometer was used to determine the time of flow of dishwashing soap at 20 °C.

Data for Water:
Time of flow: 0.23 seconds
Density at 20 °C: 0.998 g/cm³
Viscosity: 0.0101 poise

Data for Dishwashing soap:
Time of flow: 4.67 seconds
Density at 20 °C: 1.388 g/cm³

 

QUESTION: 

1. What is the viscosity of dishwashing soap?

2. From the computed viscosity of dishwashing soap, what will be its kinematic viscosity? 

3. From the computed viscosity of dishwashing soap, what will be its fluidity?
