A process fluid (Stream 1) (C p = 2100 J/kg/K) enters a heat exchanger at a rate

Question:

A process fluid (Stream 1) (Cp = 2100 J/kg/K) enters a heat exchanger at a rate of 3.4 kg/s and at a temperature of 135°C.

This stream is to be cooled with another process stream (Stream 2) (cp = 2450 J/kg/K) flowing at a rate of 2.65 kg/s and entering the heat exchanger at a temperature of 55°C. Determine the following (you may assume that the heat capacities of both streams are constant):

The exit temperature of Stream 1 if pure countercurrent flow occurs in the exchanger and the minimum approach temperature

between the streams anywhere in the heat exchanger is 10°C

The exit temperature of Stream 1 if pure cocurrent flow occurs in the exchanger and the minimum approach temperature between the streams anywhere in the heat exchanger is 10°C
