   A water turbine of expected efficiency 85% operates under 36m at a flow rate of 10m³/s. The unit weight of water is 10kN/m³. The nearest shaft power in MW is

   1. 3.06
   2. 3060
   3. 3600
   4. 850
   Show answer

   Answer: (1) 3.06

   Shaft power = ηγQH = 0.85 × 10 kN/m³ × 10 m³/s × 36 m = 3060 kW = 3.06 MW (3060 is the answer in kW, not MW).
