What is the rate of customer demand called? Takt time Which of these is the best definition of takt time? Takt time is the rate at which you need to complete a product in order to meet customer demand. It comes from the German word “Takt,” meaning beat or pulse in music. Within manufacturing, takt […]
How is soil permeability measured?
How is soil permeability measured? Soil permeability, also termed hydraulic conductivity, is measured using several methods that include constant and falling head laboratory tests on intact or reconstituted specimens. Alternatively, permeability may be measured in the field using insitu borehole permeability testing (e.g. [2]), and field pumping tests. How many test in the lab can […]
What is the concurrent engineering approach and why should project managers be aware of it?
What is the concurrent engineering approach and why should project managers be aware of it? [Concurrent engineering] brings together, from project inception, multiple individuals to address all angles of a project and enables the accumulation of knowledge and information so as to reduce downstream risks and anticipate constructability, operability, and maintainability expectations.” What is the […]
How does cathodic protection on a pipeline work?
How does cathodic protection on a pipeline work? In essence, cathodic protection connects the base metal at risk (steel) to a sacrificial metal that corrodes in lieu of the base metal. The technique of providing cathodic protection to steel preserves the metal by providing a highly active metal that can act as an anode and […]
How do you read a tube in manometer?
How do you read a tube in manometer? Measurement of Pressure with the Manometer 2-1. In its simplest form the manometer is a U-tube about half filled with liquid. 2-4. At left, equal pressure is imposed on the fluid in the well and in the indicating tube. 3-1. At left, equal pressure is imposed on […]
How do you calculate retraction speed of a cylinder?
How do you calculate retraction speed of a cylinder? The retraction speed of a cylinder rod is equal to the oil flow rate divided by the annular piston area, as Figure 2-25 shows. Since there is less volume to fill during retraction, the rod will retract faster than it extends for any given flow rate. […]
What is the difference between traction and hydraulic elevators?
What is the difference between traction and hydraulic elevators? A hydraulic elevator uses an electronic pump that pushes oil into a cylinder where the pressure is increased, pushing a piston and causing the elevator to rise. A traction elevator, on the other hand, uses a system of cables, pulleys, and counterweights to lift the cab. […]

How does methylmercury affect fish?
How does methylmercury affect fish? Bioaccumulation of Mercury Fish absorb methylmercury from their food and from water as it passes over their gills. The older and larger the fish, the greater the potential for high mercury levels in their bodies. Fish are caught and eaten by humans and animals, causing methylmercury to accumulate in their […]
