7.5 Using a T8 as a piezometer

The T8 can be used as a piezometer for measuring water over
pressure. Calculate the height of the water level with:
p
H2O
kg/dm3. [Pa] = [N]/[qm]; [N] = [kg/m qsec]; [kg] = [Pa qm/m]; [Pa] =
kg/[qqm qsec].
A water column of 100 cm causes the following pressure:
p [Pa= N/qm] = 998,205 kg/qqm x 9,81 m/qs x 1m
p = 9792,39 [N/qm x Pa qs/m /qqm x m/qs x m] = 97,92 hPa.
Accordingly 10 kPa at 20°C indicate a water column of 102,15 cm.
