Calculate the inner diameter if you are designing for a max
Civil Engineering
1.a tower is surrounded by a wall that is 10 m high and 30 m away from the base of the tower. compute the length of the shortest ladder that can stand outside the wall and lean against the tower.
2.For a steel stack that exhaust 1200 m^3/min of gases at 1atm and 400 K, calculate the inner diameter if you are designing for a maximum expected wind speed at the stack of 12m/s.
3.Assume 0.1 kg of air initially at 200 kPa and 300 K undergoes an isothermal compression process to a volume of 0.02 m3. Find the work done in the process and the final pressure. Sketch the process on a P-V diagram.
