(b) Waves with period 10 s are propagating in a water depth of 100 m. A pressure transducer located 20 m below the still water level measures a maximum pressure of 215 kN/m2 under the waves. The seawater density is 1025 kg/m3. Estimate the wave height from this pressure measurement. If 5 kN/m2 is the lowest dynamic pressure that can be measured by the transducer, at what depth below the still water level would the transducer fail to detect the waves2

solve the question given in the image.

(b) Waves with period 10 s are propagating in a water depth of 100 m. A pressure
transducer located 20 m below the still water level measures a maximum pressure
of 215 kN/m? under the waves. The seawater density is 1025 kg/m. Estimate the
wave height from this pressure measurement.
If 5 kN/m? is the lowest dynamic pressure that can be measured by the
transducer, at what depth below the still water level would the transducer fail to
detect the waves?
