WebbThe data suggest that water cannot be assigned one value to describe its ballistic effic\ iency against a shaped-charge jet. Calculations show that 500 mm of water had an elemental mass efficiency \(em\) = 3.9, 1000 mm of water had an em = 2.6, and 1500 mm of water had an em = 1.8. WebbThe MFP of air at atmospheric pressure is very short, 70 nm, but at 100 mPa (≈ 10−3 Torr) the MFP of room temperature air is roughly 100 mm, which is on the order of everyday objects such as vacuum tubes.
