Problem 5 You have gathered an experimental step response from a measurement instrument in order to assess its dynamic parameters. The measurement instrument is a pressure transducer whose output is a voltage. The pressure input stepped up from a value of 0 gage pressure to a pressure of 10 psi. a. Using the step response (on the right), estimate the parameters of the measurement system. b. Write the transfer function of the system.

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]
