Water travels through a pipe at 4 m/s. The pipe changes from a radius of 0.75 m to a radius of 1.25 m.What is the area of the 0.75 m radius pipe? What is the area of the 1.25 m pipe? What is the velocity of the water after the pipe has changed radii? How does the pressure change from the 0.75 m pipe to the 1.25 m pipe? Enter a positive number if the pressure increases, a negative number if it decreases.

Which of the following statements regarding the presented form of Bernoulli's equation are true? 1 P₁+ + = pw² + pgz₁ = P₂ + = pw² + pgzz Select one or more: U a. The flow is steady and frictionless. Ob. Flow friction is taken into account in the equation. O c. The equation describes energy conservation in a flow. Od. The middle streamline of the flow has to remain on a same level, which means the equation can only be used when zand z2 are equal. Oe. The equation has terms for kinetic energy, potential energy, and pressure. O f. The flow is transient and frictionless.
