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:
- Water at room temperature ( 300 K) enters the turbine at P1 =
- Water at at room temperature ( 300 K) leaves the turbine at P2 =
- One apartment uses 10,000 kg water per hour
- Each apartment needs 500 W power for illumination
