Fluid Mechanics Viscosity Question 171
Question: Water from a tap emerges vertically downwards with an initial speed of $ 1.0m{{s}^{-1}} $ . The cross-sectional area of the tap is $ {{10}^{-4}}m^{2} $ . Assume that the pressure is constant throughout the stream of water and that the flow is streamlined. The cross-sectional area (in $ m^{2} $ ) of the stream, 0.15 m below the tap would be: $ \left[ Takeg=10m{{s}^{-2}} \right] $
Solution:
Answer: $ \left( \mathbf{5}\times \mathbf{1}{{\mathbf{0}}^{-5}} \right) $
