Chapter 12, Problem 12.93(choose chapter or problem)
Two very large open tanks A and F (Fig. P12.93) contain the same liquid. A horizontal pipe BCD, having a constriction at C and open to the air at D, leads out of the bottom of tank A, and a vertical pipe E opens into the constriction at C and dips into the liquid in tank F. Assume streamline flow and no viscosity. If the cross-sectional area at C is one-half the area at D and if D is a distance below the level of the liquid in A, to what height will liquid rise in pipe E? Express your answer in terms of h1.

ANSWER:Problem 12.93
Two very large open tanks A and F (Fig. P12.93) contains the same liquid.

If the cross-sectional area at C is one-half the area at D and if D is a distance below the level of the liquid in A, to what height will liquid rise in pipe E? Express your answer in terms of h1.
Step by Step Solution
Step 1 of 3
The continuity equation at point C and D is:
The speed of efflux at the end of constriction D, is
is the height of the liquid at point A:
The cross sectional area at D is twice that at point C, hence the speed of efflux at C is twice of the speed of efflux at D, hence:
