Wave

Question 1

Formula for wave period

Answer 1

T = sqrt(2piwavelength/g)

Question 2

Power formula for a wave

Answer 2

P = (pg^2a^2T)/8pi

Question 3

Max steepness of a wave

Answer 3

a/wavelength = 0.03

Question 4

Name the 3 key requirements for wave technology

Answer 4

• Operate reliably in a hostile corrosive environment
• Must be able to harness low frequency cyclic waves and transfer to energy efficiently.
• Survive the 50 year storm conditions

Question 5

Describe the three main types of wave technology

Answer 5

• Passive - Guides waves to spill into reservoirs which then drain through hydro turbines to create energy.
• Relative motion - Fluid moves around a set structure which drives a rotary machine to create energy
• oscillating water column - sea water is omitted to a water chamber where it is vented to the atmosphere.
