Homework Statement
Process water with a specific heat capacity of 4.182 kJ kg–1 K–1 flows at a rate of 0.050 kg s–1 through a heat exchanger where its temperature is increased from 16°C to 85°C. Heat is supplied by exhaust gases (mean specific heat capacity 1.075 kJ kg–1 K–1) which enter the heat exchanger at a temperature of 420°C. If the mass flowrate of the exhaust gases is 0.044 kg s–1, determine their outlet temperature
Homework Equations
∆T=(TH2 –TC1)–(TH1 –TC2) ln⎛TH2 –TC1⎞
⎜ ⎟ ⎝TH1 –TC2⎠
The Attempt at a Solution
I understand the basis on how to calculate the Temperature difference and heat loss along with area however I am unsure on how to calculate the outlet hot temperature Th2 and how to rearrange this equation to find the outlet temp
Any guidance or equations that may be of use would be much appreciated
