I NEED SOMEONE TO PARAPHRASE PLEASE HELP in this lab first we continued learning about discrete ana continuous time signals and now
continuous time systems can be represented by ditterential equations, while discrete time
svstems can be represented bv diference equations or block diagrams. Then we applied what
we've learned in Matlab and some practical system examples like audio system filtering

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
