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)14 m/s C)15 m/s D)16 m/s

Bernoulli's equation: P + 1/2 * ρ * v^2 + ρ * g * h = constant. Since the pressure remains unchanged, we have 1/2 * ρ * v1^2 + ρ * g * h1 = 1/2 * ρ * v2^2 + ρ * g * h2. Solving for v2, we get v2 = √(v1^2 + 2 * g * h). Plugging in the given values, we get v2 = √(15^2 + 2 * 9.8 * 3) = 13 m/s.
