A double pipe heat exchanger consists of a 2" sch 40 steel pipe inside a 3 inch sch 40 steel pipe, 10 m long. Water at 25°C flows at the rate of 100 kg/hr through the smaller pipe while steam at 120 kPa is condensing in the annulus. The water side heat transfer coefficient is 1000 w/mk while the steam side heat transfer coefficient is 20000 w/mk. Find the exit temperature (°C) of the water and the mass flow rate of steam (kg/hr)
