Assume the temperature of the exhaust in an exhaust pipe can be approximated by T = To (1 + ae-bx) [1 + c cos(@t)], where To = 100 °C, a = 3, b = 0.03 m²¹, c = 0.066, and w = 100 rad/s. If the exhaust speed is a constant 3 m/s, determine the time rate of change of temperature of the fluid particles at (a) x = 0 and (b)x= 4 m when t = 0. DT (a) °C/s (b) Dt DT Dt i °C/s
