A pressure sensor is to be deployed at a site northeast of Appledore Island in 70 feet of water. The pressure sensor must be able to measure 3 second period waves with a pressure response factor of at least 0.1. What is the maximum depth that the sensor may be deployed

Answer:

21.65 feet

Explanation:

We have a pressure sensor that is to be deployed to the northeast of appledore.

Pressure response factor should be at least 0.1

We have pressure response factor

Kp = 1//cosh kd

To get cosh kd,

1/0.1 = 10

Using the waves table d/Lol is approximately 0.47

Lo = gt²/2pi

After inserting values,

Lo = 1.56x9 = 14.04

d/Lo = 0.47

d/14.04 = 0.47

When we cross multiply,

d = 14.04x0.47

d = 6.60m

When converted to feet's

= 21.65 feet
