section, and for the study of flow in straight and curved pipes, and through
weirs and orifices of practically any type.

A large assortment of accurate apparatus for the measurement of
quantities, velocities, and pressures, both in open and closed channels, is
available, including a variety of water meters, among them various Venturi
meters.

The laboratory is equipped with an over-shot wheel and several types
of impulse water-wheels including tangential and Girard turbines, reaction
turbines with cylinder, register, and wicket gates. The pumping machinery
includes both duplex and triplex reciprocating pumps, centrifugal pumps,
vacuum pumps, jet pumps, and the hydraulic ram.

The electric power supply is favorable to accurate work on hydraulic
machine testing. A 175 k. w. synchronous motor generator set supplies 220
volts, direct current, through four feeder lines into the laboratory. Un-
usually exact speed regulation can be obtained with noninterference of
other testing apparatus.

The regular course of instruction includes a careful selection of typical
determinations, and opportunities are offered for advanced and research
work in practical hydraulics and hydraulic machinery as well as in the more
advanced lines.

SANITARY LARORATORY. A well equipped sanitary laboratory is housed
in the Hydraulic Laboratory. The apparatus available for the use of the
students includes all modern equipment necessary in making accurate sew-
age and trade wastes analysis. The course of instruction includes work of
an advanced nature, where the student can observe for himself the analyses
studied in the theoretical courses, and at the same time carry on some re-
search work to assist in the solution of many of the present problems in
sewage and trade wastes disposal.

THE ROAD MATERIALS TESTING LABORATORY. In cooperation with the
Wisconsin Highway Commission the University offers instruction in the
testing of both bituminous and non-bituminous road materials. The equip-
ment in the laboratories is sufficient to perform all of the standard tests.

OTHER LABORATORIES. The mechanical and electrical laboratories, the
Machine Shop, as well as the laboratories of the science departments are
open to engineering students and are described elsewhere in this bulletin.
