In an adiabatic heat exchanger steam is cooled down with cooling water. Steam enters the heat exchanger at 1 MPa and 300°C leaves at 1 MPa and 140°C with mass flow rate of 2 kg/s. Cooling water enters at 100 kPa and 25°C with a mass flow rate of 75 kg/s. Determine the exit temperature of cooling water and the entropy generation of this process.

In an adiabatic heat exchanger steam is cooled down with cooling water. Steam enters the heat
exchanger at 1 MPa and 300°C leaves at 1 MPa and 140°C with mass flow rate of 2 kg/s. Cooling water
enters at 100 kPa and 25°C with a mass flow rate of 75 kg/s. Determine the exit temperature of cooling
water and the entropy generation of this process.
Adiabatik bir isi degistiricisinde su buhari soğutma suyu ile soğutulmaktadir. Isi degisticisine buhar 1MPA
ve 300°C degerlerinde girip 1MPA ve 140°C degerlerinde, 2 kg/s kutlesel debiyle cikmaktadir. Soğutma
suyu 100 kPa , 25°C ve 75kg/s debiyle girmektedir. Soğutma suyunun çıkış sicakligini ve prosesin
entropy uretimini bulunuz.
