## FAQs on Fluid Properties Video Lecture - Fluid Mechanics for Mechanical Engineering

 1. What are the common properties of fluids?
Ans. Fluids have several common properties, including the ability to flow and take the shape of their container. They also have density, viscosity, pressure, and temperature.
 2. How is density defined for fluids?
Ans. Density is a measure of how much mass is contained in a given volume of a fluid. It is calculated by dividing the mass of the fluid by its volume. The unit of density is typically expressed in kilograms per cubic meter (kg/m^3).
 3. What is viscosity and why is it important in fluid mechanics?
Ans. Viscosity is a measure of a fluid's resistance to flow. It determines how easily a fluid can be deformed or how much it resists being sheared. Viscosity is vital in fluid mechanics as it affects the flow behavior, such as laminar or turbulent flow, and plays a crucial role in various applications like lubrication, pumping, and mixing.
 4. How does pressure affect fluids?
Ans. Pressure is the force exerted by a fluid per unit area. In fluids, pressure is transmitted equally in all directions. Changes in pressure can lead to fluid flow, as fluids tend to move from areas of high pressure to low pressure. The pressure difference also affects various fluid phenomena, such as buoyancy and fluid dynamics.
 5. What is the effect of temperature on fluid properties?
Ans. Temperature influences several fluid properties. It affects the density of fluids, as most substances expand when heated and contract when cooled. Temperature also impacts viscosity, with fluids generally becoming less viscous as temperature increases. Additionally, temperature plays a role in phase changes, such as the transition from a liquid to a gas or solid state.
