The well water, which is 50 m below ground level, is pumped into the storage tank 12 m above the same level as the flow rate of 1000 kg/h. In winter, 52700 kJ/h 1 of a heater is given to the water to prevent water from freezing on the transmission line between the well and the storage tank. 25200 kJ/h 1s1 is lost fixedly from the entire system. Accept that the temperature of the well water is 273 K and calculate the temperature of the water taken into the storage tank. The power of the pump used to press the water is 1.2 kW. Only 60% of the energy given to the pump can be used.

Yer seviyesinden 50m aada bulunan kuyu suyu 1000kg/h 'lik debi ile ayn seviyeden 12m yukardaki depolama tankna pompalanmaktadr. Kn kuyu ile depolama tank arasndaki iletim hattnda suyun donmasn nlemek zere suya bir 1stcdan 52700kJ/h s verilmektedir. Tm sistemden sabit ekilde 25200kJ/h 1s1 kaybedilmektedir. Kuyu suyunun scaklnn 273K olduunu kabul ederek depolama tankna alnan suyun scakln hesaplaynz. Suyu basmakta kullanlan pompann gc 1.2kW 'r. Pompaya verilen enerjinin ancak \%60'ndan yararlanlabilmektedir
