Boundary Layer Analysis Of Casson Fluid Flow Essay

After each of the solids were completely dry, each was placed into a MelTemp device. The temperature at which each solid began to melt and completed melting was recorded.

The film Voces Inocentes was based on the true story of a young Chava and his friends growing up in El Salvador during the Salvadoran Civil War and illustrates the extreme and devastating realties of the civil war, particularly regarding the use of child soldiers. The film opens following several soldiers marching four young boys along a road in the pouring rain as they cry. The camera shows the solemn group passing a mother, who protectively guards her infant son, even picking him up as she watches with concern as the soldiers lead the young boys past. Soon, the voice of the young narrator woefully states, “I am so thirsty and my feet hurt. I have rocks in my shoes. They’re going to kill us for sure. Why do they want to kill us if we

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

[]In “Finding Flow” Mihaly Csikszentmihalyi explores the idea of what it means “to live” (544). Csikszentmihalyi compares living with his idea to flow. Throughout the “Finding Flow” excerpt, Csikszentmihalyi discusses the idea of flow is to have a clear and concise goal, provide immediate feedback, and to balance skills and action opportunities (548).

The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases from subsonic to transonic.

3. When heat flows from a warm object in contact with a cool object, do both objects undergo the same amount of temperature change?

Throughout this lab, three traps were utilized to obtain the most soil arthropods. They are as followed: berlese funnel trap, pitfall trap, and sifting through soil. The materials needed to set up a berlese funnel are a ten liter soda plastic bottle, (metal holes circular), and lastly soil. The ten liter plastic soda bottle needs to be cut across the top and bottom, making the shape of a cylinder. After putting the soil in the berlese funnel trap, by using a shovel, a heating light is required. To set up the pitiful trap a plastic small cup is required. Then a funnel is placed inside the cup so it is level with the plastic cup. Lastly, rubbing alcohol is required at the bottom of the pitiful fall trap which is necessary for the arthropods found to die. The last method used to discover soil arthropods required a metal bin, shovel, and soil.

The viscosity of room temperature is less than the colds. So it flowed a bit more faster then the colds. It flowed faster but not as fast as the hots. The velocity for team hots data was 6.8 cm/s. In the hots syrup the molecules moved the most freely and loose.

Physics explains thermal expansion as linear dimensions increasing by the same percentage with an increase in temperature. In other words, when you heat an object, that object expands and becomes larger due to the change in the object's temperature. Raising an object’s temperature, in this case, the metal lid, causes it’s molecules to move faster. The faster molecules move, the more space they occupy. If something occupies more space than it originally did, then by definition it is now bigger. Therefore, the heat exchange from water to metal heats the molecules within the lid

In the Water Phase Change Lab, my hypothesis, which stated that temperature will remain constant during a phase change based on that forces of intermolecular and kinetic energy only “battle” during a phase change, was mostly valid due to certain trends in which the temperature probe measured. We first started out with ice at around -10° C and a bunsen burner. Once the temperature exceeded 0.3° C at 0.75 minutes, traces of water became noticeable. The increase in temperature slowed down and varied around 0° C until a sudden temperature spike occurred 2.5 minutes in which made the temperature of the ice and water mixture go to 25° C. This was most likely caused due to the probe coming in contact with the bottom of the container - the region in

-The Reynolds number of this experiment was then calculated using equation (4) where c is the length of the aerofoil chord and is the dynamic viscosity of air.

the condition z1≠z2 is true if the two pressure taps are not horizontal (at different height).

The temperature-time plot gotten by applying a lumped-parameter analysis (Equation 6) to the Aluminum cylinder was compared to the plot obtained from the thermocouple located closest to center of the cylinder. This thermocouple is chosen for comparison because it is located farthest from the heating source and will have a temperature history that differs most from an ideal lumped system. With this thermocouple, we should therefore obtain the maximum error associated with applying a

The purpose of this module is to investigate hydrostatic forces on a plane surface under partial and full submersion.

Overall, the experiment succeeded that the metals show the theoretical properties. Differences existed in the mathematical calculation of the actual length. These differences, however, it can be accounted for by experimental error; more over there are uncertainty on purity of the
