A pressure gauge with a 30 KPa dynamic response range is to be to be mounted at an elevation (-z) metres below the water surface in water that is 60 m deep. Its purpose is to measure wave heights and periods. Wave heights (H) up to a maximum of 5 m are anticipated at the site, with wave periods (T) expected to range from 4 seconds (i.e. locally-generated seas) up to 14 seconds (swell). The Figure below shows a graph of the expected dynamic pressure range plotted against wave heights for wave periods of 4 sec and 14 sec respectively, calculated using linear wave theory.

After 3 months of operation, the pressure gauge stops working. A commercial diver is deployed to replace the gauge with a new one. A 1 m swell of 10 sec wave period is present olivathovendows the day the diver is in the water. At what depth would the diver experience the greatest wave-induced orbital currents, as she/he descends to the sea bed? Go to Settings to activate Windows.
