THEORETICAL BACKGROUND : Fluid: A fluid is a substance that continually deforms (flows) under an applied shear stress. Type of fluid: Newtonian fluid: A fluid that behaves according to Newton's law, with a viscosity μ that is independent of the stress, is said to be Newtonian. Non-Newtonian fluid: A non-Newtonian fluid is a fluid that does not follow Newton's Law of Viscosity. Most commonly, the viscosity of non-Newtonian fluids is dependent on shear rate. Turbine: A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator. Types: Impulse turbine: An impulse turbine is a turbine that is driven by high velocity jets of water or steam from a nozzle directed on to vanes or buckets attached to a wheel. The resulting impulse spins the turbine and removes kinetic energy from the fluid flow.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
