Ippolit Antonovich Evnevich was born in the Mogilev District of today's Bielorussia. He graduated as a physicist from the University of Saint Petersburg in 1856. In 1868 he became a professor of applied mechanics at Saint Petersburg Institute of Technology, after having there been a Lecturer from 1862. He also lectured on applied mechanics at other institutions of higher education. Evnevich was also attached to the Saint Petersburg Academy of Sciences from 1863, and to the Institute of Civil Engineers from 1886. Later, he lectured in addition at the Electrotechnical Institute of Saint Petersburg.

Evnevich was a notable Russian scientist in the fields of hydraulics and mechanics. His principal works were in hydromechanics; in 1874 he published the successful book A course in hydraulics, one of the first Russian texts in this discipline. His scientific interests included further the strength of materials, the theory of elasticity, and the dynamics of steam engines. Evnevich published a number of papers in the Engineering Periodical of Saint Petersburg, including research on the motion of viscous fluids, thereby accounting for the exchange coefficient of turbulent flow as introduced by Josef Boussinesq (1842-1929) in 1877. He also investigated the energy conservation law for these flows and observed that there are fundamental differences between ideal and viscous fluids.
