When a 13-cm pipeline is filled with air at 30'c a. what is the maximum speed (in m/s) the air could be traveling if flow were laminar? b. what would be the maximum speed (in m/s)'to maintain laminar flow if the pipeline were filled with water at the same temperature instead of air?

Consider an ideal gas at 27.0 degrees celsius and 1.00 atmosphere pressure. imagine the molecules to be uniformly spaced, with each molecule at the center of a small cube. what is the length l of an edge of each small cube if adjacent cubes touch but don't overlap?

Where should a carbon monoxide detector be mounted?

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
