By what factor would you expect the maximum power for a water turbine to be greater than an identical wind turbine?
what power is available in a flow of water with velocity of 2.8 m/s in a circular channel with diameter 10.6 m (in W)? You may assume the density of water to be 1000 kg/m3.
how much power (in W) could we hope to generate when a flow of water with velocity of 2.8 m/s drives a turbine with diameter of 10.6 m. You may assume the density of water to be 1000 kg/m3.
How much energy (in MJ) is released when there is 1 kg of mass defect? You can simplify the speed of light to be 300000000 m/s. Always check your units!
