What are boundary conditions heat transfer? The following boundary conditions can be specified at outward and inner boundaries of the region. Known temperature boundary condition specifies a known value of temperature T0 at the vertex or at the edge of the model (for example on a liquid-cooled surface). What is convection boundary condition? In heat […]

Is an engineer a scientist?
Is an engineer a scientist? Engineers are not a sub-category of scientists. So often the two terms are used interchangeably, but they are separate, albeit related, disciplines. Scientists explore the natural world and show us how and why it is as it is. Engineers innovate solutions to real-world challenges in society. Should I be a […]
What do renewable energy and non-renewable energy have in common?
What do renewable energy and non-renewable energy have in common? Renewable and non-renewable resources have many similarities. They both are resources and they both have to do with the environment. Also, we must use them wisely because if not they will disipear. They both grow on Earth, as well. How is renewable energy different from […]
What is reversible process and irreversible process in thermodynamics?
What is reversible process and irreversible process in thermodynamics? Summary. A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. An irreversible process is one in which the system and its environment cannot return together to exactly the […]
