Design a proportional control law k(s) = kp to satisfy requirements i. and iii. only. plot g(s) and l(s) = g(s)k(s) on the same bode plot using the matlab command bode. also, simulate the closed- loop system with r(t) = 1 deg/sec and n(t) = 0: 1 sin(200t).

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]
