Description: 
Studies on hydraulic turbines conducted at the Institute include 
cavitation characteristics, average flow velocities, flow during accelera- 
tion, design of rotor blades of radial-axial turbines, and design of 
hydraulic turbines. Studies on pumps include low-capacity and high-pressure 
labyrinth pumps for corrosives, airtight electric pumps for corrosives, 
feed pumps for boilers, suction capacity of screw pumps, efficiency of 
axial pumps, radial-impeller clearance effects on axial-pump performance, 
finishing of mass-produced cantilevered pumps, guide devices in centrifugal 
pumps, and stalling cavitation of centrifugal pumps. The Institute has 
also manufactured hydraulic amplifiers and studied spool-valve control 
mechanisms. 
A Trudy is published by this institute.

Description: 
VSEGINGEO conducts engineering geological research. It has been 
especially active in the analysis of natural waters and mineral ores. The 
Institute has a hydrogeological station, and at some time prior to 1961, 
sponsored a Central Asian expedition to study short-period seismic surface 
waves,
