The experiemnt is conducted by blowing dry air at 1 atm at a free-stream velocity of 2 m/s over a body covered with a layer of naphthalene. The surface area of the body is .75 m^2, and it is observed that 100 g of maphthalene has sublimated in 45 min. During the experiemnt, both the body and the air were kep at 25oC, at which the vapor pressure and mass diffusivity of naphthalene are 11 Pa and Dab=0.61*10^-5 m^2/s respectively. Determine the heat transfer coefficent under the same flow conditions over the same geometry.arrow_forwardAuto Controls Design a PID controller for thefollowing system so that the modified system satisfies the followingspecifications : 1. settling time ,ts = 1.96 s and % Overshoot Mp = 70.7 % Assume a non-dominant pole at s = -15 to solve the problem The plot the compensated andThen plot the uncompensated system in MATLAB. what can you see from the plot ? what is your observation ?arrow_forward
