how was viscosity measured in the "viscosity" lab?

directly with a viscosity meter

indirectly by measuring the distance a liquid flowed in a given time

indirectly by measuring the volume of honey

directly with a spring scale

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
