Water (density = 1 × 10³ kg/m³)flows at 15 m/s through a pipe with radius 0.040 m.The pipe goes up to the second floor of the building,3.0 m higher,and the pressure remains unchanged.What is the speed of the water flow in the pipe on the second floor? A) 13 m/s B) 17 m/s C) 166 m/s D) 14 m/s E) 6 m/s

Bernoulli's equation: P + 1/2ρv^2 + ρgh = constant. Since the pressure remains unchanged, 1/2ρv^2 + ρgh = constant. Thus, v^2 = constant - 2gh. Therefore, v is constant.

Water (Density = 1 × 103 Kg/m3)flows at 15 M/s
