stream is 9000 Pa , determine suitable dimensions (tube inside diameter and exchanger length). Assume the flow to be fully developed turbulent flow with Darcy friction factor \( f=0.184\operatorname{Re}^{-0.2}\). Consider flow to be balanced i.e. heat capacity of hot fluid is equal to
heat capacity of cold fluid. Take the following properties of air at mean temperature i.e.310 K.
