A 70 kg bicyclist is riding her 15 kg bicycle downhill on a road with a slope of 8° without pedaling or braking. The bicyclist has a frontal area of 0.45 m² and a drag coefficient of 1.1 in the upright position, and a frontal area of 0.4 m² and a drag coefficient of 0.9 in a racing position. If the downhill speed of the bicyclist (terminal velocity) can be determined when the total force acting on the "body" in the direction of movement is equal to zero, determine the percentage of down speed that she can be increased when she is in a racing position. Air temperature is 15°C and disregarding the rolling resistance and friction at the bearing.

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Task 1 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 flowin 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…

Task 1 You have been moved into the laboratory for the fluid testing for hydraulic devices and a considerable amount of research has been carried out in an attempt to understand the exact nature of the temperature variation of viscosity. Inspect the table given below and note the relative values of viscosity for each Newtonian fluid at a given temperature. Compare the results of a viscosity test and comment on why the viscosity of ethanol and water is considerably lower than motor oil and explain any discrepancies.
