A. B. For a fluid in motion, the total head will always exceed the hydraulic head (the sum of the pressure and elevation heads). C. For steady flow in a river with constant direction, depth and width, the sum of the acting horizontal forces will be in the direction of flow. Consider flow through a contraction in a pipe in addressing the following 3 statements: The mass flux in the pipe after the contraction is the same as that before the contraction.

Question

Please tell whether the statements are True or False.

A. B. For a fluid in motion, the total head will always exceed the hydraulic head (the sum of the pressure and elevation heads). For steady flow in a river with constant direction, depth and width, the sum of the acting horizontal forces will be in the direction of flow. Consider flow through a contraction in a pipe in addressing the following 3 statements: C. The mass flux in the pipe after the contraction is the same as that before the contraction. D. The momentum flux in the pipe after the contraction is the same as that before the contraction. E. The pressure immediately after the contraction is less than that immediately before the contraction.
