Water flows through a turbine. Calculate the power (M_W) transmitted by the output shaft of the turbine. The water density is 1000 kg/m³. The elevation of the upper reservoir surface is 720 m and that of the lower reservoir is 695 m. The pipeline diameter is 2.2 m, the total length is 50 m, and the mean velocity is 2.4 m/s. The friction factor is 0.25. The sum of minor loss coefficients is 4.7. The turbine efficiency is 80%. Choose the closest answer (M_W): 

(a) 1.6, 

(b) 1.7, 

(c) 2.0,

(d) 2.1, 

(e) 2.5.
