Ty just received a job offer in a new city. He is married with two small children. He and his wife go to visit the city and find a place to live. Their children will be in school in a few years. While on the trip, they visit a beautiful public park for the kids. They encounter one type of tax when they buy a few souvenir T-shirts: the shirts are on sale for $10, but Ty ends up paying $11.00 after the sales tax is added. Later, they encounter a second type of tax. When Ty and his wife meet with their real estate agent, the agent tells them that the property taxes they will pay on their new home are higher than the taxes on their old home. However, the agent says the government funds the schools in the area well, and the schools are high quality. What are the costs and benefits of the taxes that Ty and his wife experienced on this trip?

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
