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.
