Water flows straight down from an open faucet. The cross-sectional area of the faucet is 2.00 10-4 m2, and the speed of the wate

r is 0.94 m/s as it leaves the faucet. Ignoring air resistance, find the cross-sectional area of the water stream at a point 0.11 m below the faucet.

Answer: 10.79×10^-5 m^2

Explanation:

v2 = 0.94m/s

Cross sectional area(A) = 2 × 10^-4m^2

v1A1 = v2A2 (continuity equation used to compare any two points of the flow of an incompressible fluid. )

A1 = (v2A2) ÷ v1

v1^2 = v2^2 + 2as

v1 = sqrt(v2^2 + 2as)

distance below faucet(s) = 0.11m

Acceleration during to gravity (a) = 9.8m/s^2

Substituting v1 into the continuity equation :

A1 = (v2A2) ÷ sqrt(v2^2 + 2as)

v2A2 = 0.94 × 2 × 10^-4m^2 = 1.88×10^-4

sqrt(0.94^2m/s + (2×9.8m/s^2×0.11m)) =

sqrt(0.8836 + 2.156) = 1.743

A1 = (1.88×10^-4)÷1.743

A1 = 0.000188 ÷ 1.743

A1 = 10.79×10^-5 m^2

Answer: Works Progress Administration

The Works Progress Administration (WPA) was established in 1935, under the Franklin D. Roosevelt administration.  

The government created projects for which they hired persons to do work. WPA projects included some building of roads, bridges and other public projects.

There were other programs too, which connected with the WPA.  For instance, The Civilian Conservation Corps (CCC), the Soil Erosion Service (later known as the Soil Conservation Service), and the Works Progress Administration (WPA) were all involved in improving land conditions.  Working in conjunction with the National Forestry Service, the CCC and WPA participated in planting millions of trees to act as windbreaks, to prevent the kind of blowing erosion of soil that occurred in the Dust Bowl.
