SUMMARY
The average force exerted on water by a turbine blade can be calculated using the principles of impulse and momentum. Given a water stream with an incident velocity of +18.0 m/s and an exiting velocity of -18.0 m/s, along with a mass flow rate of 75.0 kg/s, the average force can be determined. The change in momentum, which is the product of mass flow rate and the change in velocity, leads to a definitive calculation of the average force acting on the water by the turbine blade.
