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 […]
What causes thermal energy transfer?
What causes thermal energy transfer? Thermal energy is transferred from hot places to cold places by convection. As the hot air above a radiator rises it pushes cooler air away from it. The cooler air eventually circulates back round to the radiator where it gets heated and the cycle continues. What is boundary condition in […]
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 […]
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 […]
What does the engineer do?
What does the engineer do? Engineers work in a variety of fields to analyze, develop and evaluate large-scale, complex systems. This can mean and improve and maintaining current systems or creating brand new projects. Engineers will design and draft blueprints, visit systems in the field and manage projects. Which branch is called Father of engineering? […]
How do you describe harmony in music?
How do you describe harmony in music? Harmony, in music, the sound of two or more notes heard simultaneously. If the consecutively sounded notes call to mind the notes of a familiar chord (a group of notes sounded together), the ear creates its own simultaneity in the same way that the eye perceives movement in […]
Can I turn my HVAC off?
Can I turn my HVAC off? Your HVAC system is better at maintaining temperatures than it is at starting from nothing and achieving a temperature. If you turn off your HVAC system completely in winter and your home temperature dips to 40 degrees, your furnace will have to run for hours to get it back […]
What is a combined heat and power system?
What is a combined heat and power system? CHP is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy—such as steam or hot water—that can be used for space heating, cooling, domestic hot water and industrial processes. What is an example of cogeneration? […]
