LABORATORY AND FIELD-WORK IN HYDRAULICS.
The equipment for this work comprises a steel tank for weir experiments
with adjustable bronze notches; a hook gauge for accurate measurement
of surface levels; a cast-iron stand pipe for experiments on efflux
with adjustable bronze orifices; a series of pipes with bends, elbows, and
tees for measuring pipe friction; and the proper manometers and gauges
for reading pressures. For the field-work the outfit of field instruments
has been enlarged by a current meter of modern construction and a set
of hollow copper ball floats for direct stream velocity measurements.
