Water (density = 1 ´ 103 kg/m3) flows at 10 m/s through a pipe with radius 0.030 m. the pipe goes up to the second floor of the building, 2.0 m higher, and the pressure remains unchanged. what is the radius of the pipe on the second floor?

density of water =

velocity of flow =

radius of pipe =

Height of second floor =

Now we can use here Bernuoli's Equation to find the speed of water flow at second floor

Now in order to find the radius of pipe we can use equation of continuity

So radius of pipe at second floor is 0.034 meter

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

come closer and become far apart and become steam/gas
