A hydropower plant will be built in a river with average flow rate (qv) of 400 m3/s and head (H) of 25 m over the plant. Ratio between maximum flow rate through turbines and river average flow rate (R) is chosen as 1.3. The plant will be equipped with three similar turbines in parallel, the rotational speed of each turbine is 150 rpm, and the runner blade tip tangential speed (U) is assumed to be 1.5 times the ideal discharge velocity with the given head. With the given information calculate: Theoretical power of the plant with the average flow rate of the river (MW)? Turbine specific speed nq? Turbine runner diameter (m)?

Question
A hydropower plant will be built in a river with average flow rate (qv) of 400 m3/s and head (H) of 25 m over the plant. Ratio between maximum flow rate through turbines and river average flow rate (R) is chosen as 1.3. The plant will be equipped with three similar turbines in parallel, the rotational speed of each turbine is 150 rpm, and the runner blade tip tangential speed (U) is assumed to be 1.5 times the ideal discharge velocity with the given head. With the given information
calculate:
Theoretical power of the plant with the average flow rate of the river (MW)?
