P1
Water moves through a constricted pipe in stead, ideal flow. At the lower
point, the pressure is P1 = 1.75 × 104 Pa and the pipe diameter is 6.0 cm.
At another point y = 0.25 m higher, the pressure is P2 = 1.2 × 104 Pa and
the pipe diameter is 3.0 cm.
Find the speed of flow at point 1.
Hint: You will have 2 unknowns (v1 and v2) which require 2 equations to
solve. One is Bernoulli's eq, another is the flow rate eq.
