The Armed Forces of Ukraine plan to lay underwater mines in a strait in the vicinity of Crimea to prevent the passage of hostile submarines. Determine the optimum spacing [mm] between the mines to be laid. Considerations:Enemy Submarines have the same Hull Length and Width as their Western Sea Wolf Model counterparts.Submarines are expected to transit the strait at a speed of 20 knots.Given the limited availability of Submarine Mines, it is intended to space them as far as possible in order to cover the largest possible area with the limited number of units in the warehouse.The Mines are so sensitive that the slightest disturbance in the surrounding water causes them to detonate.The density of sea water is different from that of fresh water.
