Understanding consequences of important physical properties of liquids
? QUESTION
Liquid A is known to have a lower viscosity and lower surface tension than Liquid B.
Use these facts to predict the result of each experiment in the table below, if you can.
experiment
Liquid A and Liquid B are each pumped
through tubes with an inside diameter of
27.0 mm, and the pressures PA and PB
needed to produce a steady flow of
2.4 mL/s are measured.
25.0 mL of Liquid A are poured into a
beaker, and 25.0 mL of Liquid B are poured
into an identical beaker. Stirrers in each
beaker are connected to motors, and the
forces FA and FB needed to stir each liquid
at a constant rate are measured.
predicted outcome
OPA will be greater than PB
OPA will be less than PB
OPA will be equal to PB
It's impossible to predict whether PA or PB will
be greater without more information.…
