Before studying Fluids and Heat Transfer, students should have a strong foundation in engineering mechanics, particularly fluid statics and basic thermodynamics. A solid understanding of mathematics, including calculus, differential equations, and vector calculus, is essential for analyzing fluid flow and heat transfer problems. Knowledge of physics, especially mechanics, energy, and properties of matter, helps in understanding pressure, density, and temperature effects. Familiarity with material properties and basic chemical principles is useful for thermal conductivity and viscosity concepts. Additionally, exposure to computational tools and problem-solving techniques aids in modeling and simulating fluid and thermal systems.
