Bernoulli's Theorem
Q: Water at a pressure of 3.8 atm at street level flows into an office building at a speed of 0.50 m/s through a pipe 4.2 cm in diameter. The pipes taper down to 2.6 cm in diameter by the top floor, 20 m above. Calculate the flow velocity and the pressure in such a pipe on the top floor. Ignore viscosity. Pressures are gauge pressures. flow velocity
