HYDROPOWER
Understanding Open-Channel Flow Equations for Hydro Applications 24
Accurately measuring average velocities in channels or culverts with surfaces
open to the atmosphere has been a challenge for ages. Chezy and Manning
developed equations for the task, but determining roughness coefficients for
the calculations is an imprecise science. A lab experiment may improve the
process.
ENERGY STORAGE
Analysts: Storage a Matter of Dollars and Sense
Energy storage is proving its value, beyond being able to provide reliable
power when needed. Utilities are finding the economic benefits are much
greater, enabling savings in several areas of operation.

ENERGY-WATER NEXUS
How the Clean Energy Transition Is Intensifying
the Energy-Water Nexus
The world is transitioning to cleaner forms of energy, but a scarcity of water
in some regions could put stress on power generators, and slow the growth
of clean technology.
GENERATOR MAINTENANCE
How to Examine Generators with Visual Inspection Robots
Futuristic? Perhaps it sounds that way, but miniature robots are here, and
have been proven as an efficient way to inspect generators, avoiding downtime
and the costs of other inspection methods.
GAS TURBINE
Safer and More Efficient Gas Turbine Coupling Maintenance
32
An alternative method for performing routine maintenance on the GE 7FAclass
gas turbine coupling saves time, is safer, and improves the disassembly
and reassembly process during both planned and unplanned outages.
EQUIPMENT SHOWCASE
Pumps, Valves, and Fittings
The equipment showcase section includes products from a variety of vendors
that serve the power generation industry. This month the focus is on pumps,
valves, and fittings.
