scientimate.pressureresponse

Kp, f = scientimate.pressureresponse(f, h, heightfrombed, kCalcMethod='beji', dispout='no')

Description

Calculate a pressure response factor

Inputs

f

Frequency in (Hz)

h

Water depth in (m)

heightfrombed

Height from bed that Kp calculated at in (m)

kCalcMethod=’beji’

Wave number calculation method

‘hunt’: Hunt (1979), ‘beji’: Beji (2013), ‘vatankhah’: Vatankhah and Aghashariatmadari (2013)

‘goda’: Goda (2010), ‘exact’: calculate exact value

dispout=’no’

Define to display outputs or not (‘yes’: display, ‘no’: not display)

Note: inputs can be as a single value or a 1-D vertical array

Outputs

Kp

Pressure response factor

f

Frequency (Hz)

Examples

import scientimate as sm
import numpy as np

Kp,f=sm.pressureresponse(0.2,1,0.2,'beji','no')

Kp,f=sm.pressureresponse([0.2,0.25],[0.5,0.6],0.2,'exact','yes')

Kp,f=sm.pressureresponse(np.array([0.2,0.25]),np.array([0.5,0.6]),0.2,'exact','yes')
