 The Water System |
The pressure of a city's main water line is much higher than the pressure in the water line of apartments. It is suggested that a hydraulic turbine be installed to utilize the water pressure to run an electric motor which can be supplied to the lighting system of the apartments. Is the power generated by the turbine enough to light the apartments? What is known:

|
|
Determine the power that could be produced by this hydraulic turbine. | |
| Approach |
||
|
Consider the turbine as a control volume. It is a one-inlet-one-exit system. The flow is steady. The energy balance is:
