IB Physics: Solutions

1. The diagram below shows a proposal for a wave power generator. Two floating tanks are joined together with a pipe that contains a turbine which is connected to a generator. The tanks are positioned so that when one is on the crest of a wave the other is in a trough. Estimate the power generated given the following data. Tank volume = 10m3 Wave amplitude = 4m Wavelength = 20m Wave velocity = 5ms-1 Efficiency = 20%
