HW 1.2

The homework assignment explores these topics, demanding a thorough application of
the equations that we learned in Chapter 3 around pressure. In tackling the 12 assigned problems,
an emphasis was placed on the visualization of each scenario, requiring a comprehensive
understanding to truly understand the questions. Employing the learned equations was not
merely a computational exercise but a process that involved delving into the core of each
problem, enhancing our grasp of the underlying principles

HW 1.3

Chapter six discussed the actions of fluid flow systems, to study moving a specific amount of fluid from one place to another. In chapter seven, we learned in depth applications revolving around Bernoulli’s equation. It represents a quantity of energy per unit weight of fluid flowing in the system. In these homework problems, we observed how to manipulate the variables in the equation, to find the flow rate, pressure, and other values embedded in the equation. Determining power from pumps and turbines helped us apply Bernoulli’s equation as well. Energy loss, energy added, and energy removed were big in this chapter, due to the transfer of energy through a pump. As shown in our homework questions, a lot of the time all of the variables used in the general energy equation can be zero or canceled out, turning the problem into Bernoulli’s equation.

HW 2.1

In this homework assignment we learned about the forces created by static fluids exerting pressure on their containers. We also learned about buoyant forces created by the force of a fluid pushing up on an object that is either partially or fully submerged. The weight of the object is compared to the buoyant force in order to determine whether it will be fully submerged, partially submerged, neutrally buoyant, or not buoyant. Another thing we learned and solved was the effects of a fluid being exerted on a curved surface instead of a straight and flat one. We used the formula developed in class for this purpose to assist us in the calculations and to present complete and correct answers.

HW 2.2

Chapter 16 was mostly focused on forces using Newton’s Second Law. When using velocity as a vector quantity, as magnitude and velocity change due to the flow of fluid, this results in a change in equal and opposite force. We learned from completing the problems below that a force is required to accomplish the change when direction or speed are deflected by a fluid stream. For a real life example of these practices, it can be used when looking at compressed air coming out of a nozzle being used to move products in a factory. In Chapter 17, we were introduced to lift and drag, which are important when analyzing the behavior of a body in fluid. Drag is the force on the body caused by the fluid that resists motion (opposes the direction of fluid flow), and lift is the force caused by the fluid in the direction perpendicular to the travel path of the body (net force in upward direction). These can occur simultaneously and the concepts are similar regardless of the phase they’re in.

HW 2.3

In fluid mechanics, we learned about open channel flow and measurement devices, such as the orifice plate, the Venturi meter, flow nozzles, and more. Open channel flow is classified into uniform or varied open-channel flows, as well as steady or unsteady. We use the hydraulic radius to calculate the Reynold’s Number for open channels to determine the type of flow we are dealing with. We may also calculate the Froude number to find our flow’s criticality. Hydraulic jumps are also discussed and we calculate the energy loss in the jump as well. In the next chapter, we learn about the needed tools in order to measure qualities of our fluids such as flow rate and velocity (though velocity is rarely required in industry). Orifice meters are simply a plate with a certain shape hole cut into it, while variable head meters such as the Venturi Meter are more elaborate. Both require Bernoulli’s equation to calculate the properties at that point in the fluid. We went over how to perform the requisite calculations to design these instruments.

HW 3.1

This week we learned about series pipeline flows and how to apply Bernoulli’s equation to them. As a class, we learned how to iterate to find these variables when guessing some of them, and make the iteration converge towards an answer. We also went over using the energy equation, identifying laminar and turbulent flow, and finding the friction losses in pipes and fitting. Due to the numerous real-world systems using different elements, we had to learn how to combine these using calculations (elbows, enlargements, reductions etc).  Each valve, fitting, or change in the size or direction of the flow path causes energy losses in the system.

HW 3.2

What we learned: For chapter 11, we learned about the specific aspects of fluid flow in pipes and tubes. Using the energy equation, we were able to identify laminar and turbulent flow, friction losses in pipes and fittings, and minor losses due to friction. In chapter 12,  we focused on parallel and branching pipe systems, and how the fluid flows through the pipelines. This concept explains how fluids can flow through several pipes at once, and be distributed using control valves. We learned how to approach parallel piping systems and calculate various parameters of the system such as flow rate through each branch, total flow rate of the system, and pipe diameter. The method we learned to use in these chapters is known as iteration and it allowed us to converge on a solution through successful approximations and error reduction strategies.

HW 3.3

This week in fluid mechanics we learned about pumps, pump head, impeller sizes, cavitation, and were also given the chance to view and feel a real pump impeller. We also talked about pump selection, learned to use a pump performance chart, and began on our pump selection project.Please either copy or embed your short reflective essay for each group of HW assignments.
