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?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
