The crew of US submarines work on an 18-hour cycle rather than a 24-hour day. They divide into three ‘watches’, each working for 6 hours, with a meal break for the half hour immediately before and another for the half hour immediately after work. The watches change at 05:30, 11:30, 17:30 and 23:30 Universal Time, no matter where in the world they are.
How much time for meal breaks does a member of the crew get in a 72-hour (3-day) period?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
