"Even though the Q is a factor plugged into the formula, there are "Q
meters" for testing the actual Q of a built component-network. After the
tank is complete, or just the tank coil itself, the actual Q can be
found with the meter and then compared to the value you arrived at from
the formulas. Most LCR meters have the capacity to test the Q of a
component or circuit. There are more accurate Q meters available though.
So david is right on the money by his answer."

Ouch,

The 'actual Q' of a plate tank circuit is hardly at all related to what
we refer to as the 'operating Q' of the same. The operating Q is mainly
just the L/C ratio used. Do I understand your statement above correctly?
Using a Q meter will merely give you the Q of the circuit, which is
many, many  times higher than operating Q.
