Fluid dynamics

If layers of fluid have frictional force between them, then it is known as viscous.

• TRUE

• FALSE

According to equation of continuity, when water falls its speed increases, while its cross sectional area decreases.

• TRUE

• FALSE

If every particle of fluid has irregular flow, then flow is said to be laminar flow.

• TRUE

• FALSE

If every particle of fluid follows same path, then flow is said to be turbulent flow.

• TRUE

• FALSE

According to equation of continuity, product of area of pipe and speed of fluid along pipe is equals to 1.

• TRUE

• FALSE

Bernoulli’s Principle explains how an airplane can stay aloft.

• True
• False

Bernoulli's principle states that the pressure in a fluid ____________as the fluid's velocity _____________

• decreases, decreases
• increases, increases
• decreases, increases
• goes up, goes up

The volume of fluid that flows past some cross-section of a vessel in a time rate of flow (J).

• Time rates

• Acceleration

• Rate of Flow

It is fluid entering the region between cross-sections. If the pipe size varies, the speed of a liquid also varies so as to keep Q constant,

J_in = J_out
