Water circulates throughout a building. if the flow speed and pressure in a 2.2cm-radius pipe on the top floor are 1.5m/s and 2.3*10^5 Pascals, What is the pressure and radius of the pipe two floors below (6.2m lower) if the flow speed there is 0.45m/s? Assume the pipes are cylindrical and their cross-sections are circles.
