question 7

Essay

A 10 m diameter tidal turbine is placed in an inlet and operates with a coefficient of performance of $0.3$ . During a tidal period of $12.4$ hours, the tidal current in the inlet varies from $3.5 \mathrm {~m} / \mathrm { s }$ in one direction to $3.5 \mathrm {~m} / \mathrm { s }$ in the opposite direction. If it is assumed that the change in tidal current velocity is linear in time, what is the total energy output of the turbine during one tidal period.
