Water (γwater = 9810 N/m3) drains from the reservoir higher to the bottom, both with constant levels, by a pipe with a diameter equal to 75 mm, passing a turbine to power generation. Knowing that the total load loss between sections (1) and (4) is equal to 2.0 m and where the flow rate is equal to 12 L/s;  can determine:

  1. The power on the turbine shaft in kilowatts (kW), whereas the performance of the machine is 75%. Consider that V1 ≈ 0; V4 ≈ 0.
  1.  If the static pressure in section (3) is known, equal to 205 kPa, determine the piezometric (CP) and the total energy in this section. Also calculate the CP and the total energy in (2).

Data: ℎ1 = 10 ?; ℎ2 = 20 ?; ℎ3 = 5 ?.
