10.26 The velocity of the water jet driving this impulse turbine is 45 m s. The jet has a 75-mm diameter. After leaving the buckets the absolute velocity of the water is observed to be 15 m s in a direction 60 to that of the original jet. Calculate the mean tangential force exerted by the jet on the turbine wheel and the speed (rpm)

of the wheel.
