# Fluid Mechanics Basic Concepts & Principles

Fluid Mechanics Basic Concepts & Principles – Bernoulli’s Principle: For a fluid to flow smoothly, the sum of the velocity (P), the kinetic energy per unit volume (ρ v 2/2) and the potential energy (ρ g h) remain constant. . because of the conflict. Consider the fluid that initially lies between B and D. In the infinite time interval Δt, this fluid would have moved. – Suppose v 1 = velocity at B and v 2 z velocity at D. Initial distance the water moves from C = v 1 Δ t. – At the same distance the internal fluid is displaced by D at E = v 2 Δ t. W 1 = P 1 A 1 (v 1 Δ t) W 2 = P 2 A 2 (v 2 Δ t) W net = W 1 – W 2 = (P 1 A 1 v 1 Δ t – P 2 A 2 v 2 Δ t) For continuous equation Av = constant. – P 1 Δ V 3 Pass Δ V (where A 1 V 1 Δ t = Δ V and A 2 v 2 Δ t = Δ V) W = ( P 1 – P 2 ) Δ V to balance (a) Part of this The process leads Kinetic energy, Δ K = (2 1) m (v 2 2 – v 1 2) and the distribution of potential energy, Δ U = m g (h 2 – h 1). – Total energy change Δ E = Δ K + Δ U = (2 1) m (v 2 2 – v 1 2) + m g (h 2 – h 1) eq.. (i) ρ = m/V or n = ρ V Δ m = ρ Δ V enter eq (i) Δ E = 1/2 ρ Δ V (v 2 2 – v 1 2) + ρ g Δ V (h 2 – h 1) equation – Using the work energy theorem: W = Δ E (ρ p 1 P 2) Δ V = (1/2) ρ Δ V (v 2 2 – v 1 2) + ρ g Δ V (h 2 – h 1) ( From (a ) and (b)) P 1 – P 2 = 1/2 ρ v 2 2 – 1/2 ρ v 1 2 + ρ g h 2 – ρ g h 1 P 1 + (1/2) ρ v 1 2 + ρ g h 1 = (1/2) ρ v 2 2 + ρ g h 2 P + (1/2) ρ v 2 + ρ g h = constant. Torricelli’s Law: Torricelli’s law states that the velocity of water leaving an orifice is equal to the velocity it would achieve if it fell freely for a distance equal to the height of the free surface of the water above the orifice.

With roots in physics and mathematics, Mechanical Engineering is the foundation of the mechanical sciences: civil engineering, scientific and technical equipment, mechanical engineering and aeronautical engineering. The skill machine provides the “building blocks” of stats, power, material strength, and water effects. Mechanical engineering is a discipline that aims to solve mechanical problems using a combination of mathematics, science and technology. Physical principles based on current research are emphasized.

Engineering Mechanics students are also encouraged to engage in postgraduate research with their faculty. As a result, Mechanical Engineering students are prepared for early careers in a variety of fields, including the aerospace, electronics, automotive, industrial, software and computer industries. Our ABET accredited programs provide excellent post-secondary preparation in a variety of technical fields.

On the page below is a semester-by-semester overview of the courses required in the Engineering Mechanics program. This page is provided to enable students and advisors to view pre-, co-, and post-requirement videos related to specific courses in the program. This is a tool that allows you to understand how courses are integrated across our programs to provide guidance on course enrollment.

Please begin by selecting the appropriate course page to access the Annual Catalog. With the permission of the department, students can change to the new catalog year if the degree changes. Students may not transfer to an older year and may not mix and match requirements between catalog years. Students can request a catalog change each year using the Annual Catalog – Change Request form.

This part of the curriculum helps the student to prepare himself by choosing a second course, a group of technical courses in mechanics and closely related subjects.

Every second class includes two required courses and two additional courses from the list of approved courses. For every second class, see i
