Laboratory clean rooms are often kept at a slightly higher pressure than ambient pressure in order to flush out particulates and keep dust from getting in. If the pressure in such a room is equivalent to 1 mm water greater than the surrounding rooms, with what velocity will air exit under a small crack in the door? Assume that viscous effects are negligible, i.e., that no energy is lost in the flow
