Learning Outcomes of the course unit | By the end of the course, the students should be able to:- Define and Calculate the physical properties of Hydraulic fluids and explain how these properties can affect Fluid Power.
- Utilize basic physical law principles to explain the concepts of energy and power and derive the equations estimating these quantities in Hydraulic Systems.
- Calculate fluid rates, velocities, speed of hydraulic cylinder using the continuity equation and apply Bernoulli’s equation to determine the energy transfer within a hydraulic system.
- Explain the significance of Reynolds number and how it can be used to distinguish between Laminar and Turbulent flow.
- Define types of pumps (gear, vane, and piston), describe their pumping action and explain their operation.
- Explain the function and use of pneumatic components and solve problems related to Directional Control Valves, Regulators, Excess Flow and Sequence Valves.
