Question 3: A Pelton turbine is a turbine working under atmospheric pressure and which rotates thanks to water hitting its blades (see figure). The operation of the Pelton turbine can be modeled using RTT. Formulate the expression quantifying the forces acting over one blade of the Pelton turbine. You need to consider that the blade moves at a velocity w and the water travels with a velocity v. The water flow and deflector has a diameter d and the flow rate is Q. Disregard gravity and viscosity forces. WATER 5 CA
