A chemistry graduate student is designing a pressure vessel for an experiment. The vessel will contain gases at pressures up to 110.0MPA . The student's design calls for an observation port on the side of the vessel. The bolts that hold the cover of this port onto the vessel can safely withstand a force of 4.70
Calculate the maximum safe diameter w of the port. Round your answer to the nearest 0.1cm
