Question

How high would the level be in an alcohol barometer at a pressure of 0.72 atm? The density of alcohol is 0.79 × 10^3 kg/m^3, and 1 atm = 1.013 × 10^5 N/m^2. Express your answer to two significant figures and include the appropriate units. Water at a gauge pressure of P = 3.2 atm at street level flows into an office building at a speed of 0.72 m/s through a pipe 5.0 cm in diameter. The pipe tapers down to 3.0 cm in diameter by the top floor, 16 m above (Figure 1). Assume no branch pipes and ignore viscosity. Calculate the flow velocity in the pipe on the top floor. Express your answer to two significant figures and include the appropriate units. Calculate the gauge pressure in the pipe on the top floor. Express your answer to two significant figures and include the appropriate units.
