Question

From point 1 to point 2, the potential energy density of the water increases, the kinetic energy density of the water increases, and the pressure energy density decreases.

From point 1 to point 2, the potential energy density of the water increases, the kinetic energy density of the water decreases, and the pressure energy density remains the same.

From point 2 to point 4, the potential energy density of the water decreases, the kinetic energy density of the water decreases, and the pressure energy density increases.

From point 2 to point 3, the potential energy density of the water remains the same, the kinetic energy density of the water decreases, and the pressure energy density increases.

From point 2 to point 3, the potential energy density of the water remains the same, the kinetic energy density of the water increases, and the pressure energy density decreases.

From point 1 to point 3, the potential energy density of the water increases, the kinetic energy density of the water remains the same, and the pressure energy density increases.

From point 2 to point 4, the potential energy density of the water decreases, the kinetic energy density of the water decreases, and the pressure energy density decreases.

From point 3 to point 4, the potential energy density of the water decreases, the kinetic energy density of the water remains the same, and the pressure energy density increases.

From point 1 to point 2, the potential energy density of the water increases, the kinetic energy density of the water increases, and the pressure energy density decreases.

Water is flowing through the pipe shown below. 2 3 4 The area of the pipe at point 1 is A The area of the pipe at point 2 is A. The area of the pipe at point 3 is A3. And the area of the pipe at point 4 is A4. While evaluating the statements below, take A,-A3 > A4 >A2. Ignore viscosity and assume that the water fills the pipe completely at all locations Which of the following statements are true? More than one may be.

Explanation / Answer

According to the Bernoulli equation following statements are correct.

Velocity increses then pressure will be lower.

Velovity decrease then pressure will be higher
