The Hydraulic Institute (HI) has recently added two new standards to its ANSI/HI Pump Standards. The first is the American National Standards for Air-Operated Pumps. This standard applies to air-operated pumps driven by a compressed gas (usually air) from an outside source and includes sections such as types, configurations, and nomenclature; definitions, design and application; and installation, operation, and maintenance. The second standard, the Air-Operated Pump Test Standard, applies to testing air-operated diaphragm and bellows pumps. It records test results and offers a uniform procedure for mechanical and other pump performance tests. For more information visit www.pumps.org.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
