A.) If somehow you could attach a light to a fluid particle and take a time exposure, would the image you photographed be a pathline or streakline? Explain from definition of each.
Problem 3: Smoke and Steam
One of the most enduring images
of the Industrial Revolution is a
steam locomotive with a large
plume of smoke and ashes
streaming from the smokestack.
To classify this flow, think of
wind on a stationary train (not a
train moving in stationary air).

You are employed as a mechanical engineer within an unnamed research center, specializing in the development
of innovative air conditioning systems. Your division is tasked with providing computer-based modeling and
design solutions using computational fluid dynamics through ANSYS software. Your primary responsibilities
involve the analysis of horizontal channel dynamics to meet specific criteria. Under the guidance of your
immediate supervisor, you have been assigned unique responsibilities within an ongoing project. As a member of
the research team, your role includes constructing an appropriate model and executing a sequence of simulation
iterations to explore and enhance channel performance. Figure 1 provides a visualization of the horizontal channel
under consideration. Consider 2D, incompressible, steady flow in a horizontal channel at a Reynolds number of
150. The schematic below illustrates the channel flow, not drawn to scale. For simplicity, neglect gravity. The
channel's…

Which ONE of these scenarios could you appropriately use Bernoulli's equation on?
