h is the height of the nozzle. dddd is the diameter of the tank nozzle.
NOTE!
If h < d

h < d, then the top dead zone (A1) is equal to the top dead zone for the probe only. Refer to the
table that follows.
If h

, then the top dead zone (A1) is equal to the tank nozzle height plus the top dead zone for
the probe.
NOTE!
The dimensions of the tank nozzle have no effect on the top dead zone of the coaxial probe.
