CT-213 Fluid Mechanics 4 (3+1)
The flow of fluids is important in many applications ranging from blood flow in the human body to the air flow over the wing of a jet aircraft and water flowing in pipes, canals and rivers. As a result, fluid mechanics is not only the providence of the civil engineer, but is truly a multi-disciplinary field attracting researchers in mechanical engineering, chemical engineering, materials science, petroleum engineering, environmental science, meteorology, geology, and astronomy. This course will help students in understanding the nature of fluid statics, in particular dealing with problems related to hydrostatic forces and to analyze the problems related to elementary fluid dynamics especially for incompressible flows using Bernoulli equation in particular. Students will develop skills to use flow Measurement devices like ventrimeter and Pitot tube. Students will characterize and determine the forces resulting from the interaction of flow with immersed bodies. In addition this course will enable students to solve problems relating to pipe flow and open channel flow.
