Why is it important for an engineer who is designing a new home cooling heating system to have knowledge about the transfer of heat?
Why is it important for an engineer who is designing a new home cooling heating system to have knowledge about the transfer of heat? Heat gradient is important for heat transfer between systems because heat travels from the warmer system to the cooler system. The right medium for heat transfer is also important for this […]
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 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 […]
