Question
The turbine in the sketch has a flow rate \( Q = 100 \, \text{m}^3/\text{s} \) and the outlet has a circular cross-section of diameter 2m. If the total head of the reservoir is 100m, calculate: (a) The power output \( P_T \) (in Watts) if the head loss is 20m. (b) The pressure difference across the turbine. **Diagram Explanation:** The diagram shows a reservoir with a vertical water column of height 100m. Attached to the reservoir is a turbine. The water flows out from the reservoir through the turbine to an outlet with a circular cross-section of diameter 2m. The flow rate is represented by the symbol \( Q \).
