In order to measure the air speed in a pipe of radius R, you construct a device which tapers the pipe radius from R to R/2 so that the airflow then passes over R R/2 one end of a U-tube filled with water (not moving) as shown. (Problems 6-8) 6. If the air speed on the right side of the device (where the pipe radius is R) is equal to vo, find an expression for the airspeed on the left side (radius R/2) in terms of vo.

Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing. 

Question

Question 7

In order to measure the air
speed in a pipe of radius R, you
construct a device which tapers
the pipe radius from R to R/2 so
that the airflow then passes over
R
R/2
one end of a U-tube filled with
water (not moving) as shown.
(Problems 6-8)
6. If the air speed on the right
side of the device (where the
pipe radius is R) is equal to vo,
find
an expression for the
airspeed on the left side (radius
R/2) in terms of vo.
7. The difference in water height between the left and right side of the U-tube is 9.6 m. Find a value
for the difference in pressure between the two sides.
