Scales (weigh scales, scales, etc.) are devices to measure weight or calculate mass. Spring balances or spring scales measure weight (force) by balancing the force due to gravity against the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the weight due to the mass of an object against the weight of a known mass or masses.

Financing the Future

Financing the Future

Water remains a scarce resource throughout the country. But it’s important, even for utilities that aren’t serving drought-stricken areas, to make sure that they are getting paid the right amount for the water they are delivering. It’s important, too, that they quickly identify and repair costly leaks throughout their systems.

The Physics of CHP Cogeneration and Heat Engine Efficiency

The Physics of CHP Cogeneration and Heat Engine Efficiency

How does CHP work? To understand CHP you have to begin with the Carnot cycle, and how it describes the function and efficacy of any heat engine. The thermodynamic Carnot cycle (proposed by Nicolas Carnot in 1824) is a four-stage process that describes the reciprocal operations of a heat engine

Tools for Compaction

Tools for Compaction

Soil compaction is the removal of air voids from soil by applied force in such a way that it conditions or compacts soil beneath or next to the construction, resulting in a denser soil with the ability to hold greater weight, points out Fred Paul, Wacker Neuson sales engineer and

All About the Cycle Stop Valve (CSV)

All About the Cycle Stop Valve (CSV)

The cycle stop valve opens and closes like a ball valve—it uses a spring to push it open and then a diaphragm will push it closed. The beauty of this is that the customer sets the valve at the required outgoing pressure, and that’s where it stays. So, let’s say

Invisible Tech

Innovations seem to come at us at all corners, and at an ever-escalating pace—cell phones, new fuel cars, new efficient heating, and appliances that seem to do everything but feed your pets a balanced diet and mow your lawn remotely. The truth is, some gadgets actually do perform those functions.

Editor’s Comments: Making the Grade

Back in the 7th grade I once got a C+ on an algebra test. It was a hard mid-term, and no one in my class had higher than a B+. I did better than a lot of other kids. So if we were graded on a curve, I would have

California Takes Strong Steps Toward Making Water Conservation a Way of Life

State officials today released a comprehensive plan to formalize Governor Brown’s 2016 Executive Order on “Making Water Conservation a California Way of Life.”

The plan sets a strong path toward achieving the objectives of the order: using water more wisely, eliminating water waste, strengthening local drought resilience, improving agricultural water use

Schneider Electric, the global specialist in energy management and automation, today unveiled an advanced microgrid at its Boston One Campus (BOC), the company’s North American headquarters in Andover, Massachusetts. The microgrid was built by Schneider Electric and REC Solar,

A New Roadmap to Reduce Coastal Risk

A New Roadmap to Reduce Coastal Risk

There is a saying that the only thing constant in life is change. In the realm of coastal environments, nothing could be more true. The shifting winds, the tides, and rains are what has created the often beautiful vistas of coastal landscape, the diversity of habitats and ecosystems: stones ground
