Kararlı durumda hava bir kompresöre 100 kPa basınç 27°C sıcaklık ve 30 m/dk debisinde girmekte 230 kPa basınç ve 127°C sıcaklığında çıkmaktadır (Şekil). Hava daha sonra bir isı değiştiricisine girmekte sabit basınçta 77°C sıcaklığında çıkmaktadır. İsı değiştiricisinin diğer tarafında su dolaşmaktadır. Isı değiştiricisine suyun giriş sıcaklığı 20°C çıkış sıcaklığı 40°C'dir. Çevreyle herhangi bir isı transferi yoktur. Kinetik ve potansiyel enerji değişimleri ihmal edilmektedir. a) Kompresörün gücünü (kW) ve soğutma suyunun kütlesel debisini (kg/s), b) Kompresör ve isı değiştiricisi için entropi üretimini (KWIK) bulunuz. At steady state conditions, air enters a compressor at 100 kPa pressure, 27 C temperature, and 30 m/min flow rate, and exits at 230 kPa pressure and 127C temperature (Figure). Then, the air enters a heat exchanger and leaves it at 77 C temperature, at a constant pressure. Water circulates on the other stream of the heat exchanger. The water inlet temperature of the heat exchanger is 20 C and the outlet temperature is 40 C. There is no heat transfer with the environment. Kinetic and potential energy changes are negligible. a. Find the compressor power (kW) and the mass flow rate of the cooling water (kg/h). b. Find the entropy generation (kW/IK) for the compressor and heat exchanger.
