- 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.A fluid with specific weight Golb and viscosit y 8.4x10-51b-s flows through the ft3 pipe- ft 2 If pressure drop over the length of the pipe is 2-816 ft² determine the average Velocity of the fluid.
