Water exits a pipe vertically as a free jet with initial diameter d = 1.0 cm and initial (unknown) speed V₁. The jet strikes a circu- lar flat plate that has diameter D = 10 cm and is located a distance h₁ = 20 cm above the pipe exit. Assume the flow geometry is axisym- metric, with the water leaving the plate radially with average speed V₂ through an area (shaped like a ring) with height h₂ = 0.4 mm. At the center of the plate is a static port manometer containing (still) water. Determine the steady flowrate Q and the constant height H. Hint: Start by using the fact that Q = AV is a constant to relate the (average) speed leaving the pipe, V₁, to the (average) radial speed leaving the plate, V₂.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

16. Water exits a pipe vertically as a free jet with initial diameter
d = 1.0 cm and initial (unknown) speed V₁. The jet strikes a circu-
lar flat plate that has diameter D = 10 cm and is located a distance
h₁ = 20 cm above the pipe exit. Assume the flow geometry is axisym-
metric, with the water leaving the plate radially with average speed
V₂ through an area (shaped like a ring) with height h₂ = 0.4 mm. At
the center of the plate is a static port manometer containing (still)
water. Determine the steady flowrate Q and the constant height H.
Hint: Start by using the fact that Q = AV is a constant to relate the
(average) speed leaving the pipe, V₁, to the (average) radial speed
leaving the plate, V₂.
