Exhaust gases from a wire processing oven are discharged into a tall stack, and the gas and stack surface temperatures at the outlet of the stack must be estimated. knowledge of the outlet gas temperature tm o is useful for predicting the dispersion of effluents in the thermal plume, while knowledge of the outlet stack surface temperature ts'0 indicates whether condensation of the gas products will occur. the thin-walled, cylindrical stack is 0.5 m in diameter and 5 m high. the exhaust gas flow rate is 0.5 kg/s, and the inlet temperature is 500 degree c. the ambient air temperature is 4 degree c. calculations that are a little beyond where we are now in tf1 show that the average surface heat transfer coefficient in the outside surface is h0= 14 w/m2 k, and the inside heat transfer coefficient is hi= 10 w/m2 k. the thermal resistance of the stack wall itself may easily be neglected. estimate the outlet gas and stack surface temperatures for the given conditions.

Jason and mia are both running in a race. as they approach the finish line, you being the physicist that you are decide to time how long it takes them to reach the end of the race. when you start your stop watch (you can take this as time t = 0 s) you notice that mia is an unknown distance d ahead of jason and both are moving with the same initial velocity v_0. you also notice that jason is accelerating at a constant rate of a_j, while mia is deaccelerating at a constant rate of -a_m. jason and mia meet each other for the first time at time t = t_1. at this time (t = t_1) jason's velocity is two times that of mia's velocity, meaning v_j (t_1) = 2v_m (t_1). a) draw the position vs. time graph describing mia's and jason's motion from time t = 0 to time t = t_1. clearly label your axes and initial conditions on your graph. b) draw the velocity vs. time graph describing mia and jason's motion from time t = 0s to time t = t_1. clearly label your axes and initial conditions on your graph. c) how long from when the stop watch was started at t = 0s did it take mia and jason to meet? express your answer in terms of know quantities v_0, a_m, and a_j. d) when the stop watch started at time t = 0s, how far apart, d, were mia and jason? express your answer in terms of know quantities v_0, a_m, and a_j.
