0 1 . 3 The mass of seawater passing through the tidal turbine each second is 824 000 kg.
The density of seawater is 1030 kg/m3.
Calculate the volume of seawater passing through the tidal turbine each second.

The speed of the tide or the speed of the wind past a turbine is called the box
‘flow speed’.
Figure 2 shows how the power output of a tidal turbine compares with a wind turbine
for different flow speeds.
Figure 2
0 1 . 4 As flow speed increases, power output increases.
Give two other conclusions that can be made using information from Figure 2.
[2 marks]
1 there is no power output till 0.25m/s flow speed
2 there is a non linear corelation between power and flow speed
