Problem 3 (25 Marks): Heated air at 1 atm and 100F is to be transported in a 400-ft-long circular plastic duct at a rate of 12 ft /s. If the head loss in the pipe is not to exceed 50 ft, determine the minimum diameter of the duct. The density, dynamic viscosity, and kinematic viscosity of air at 100F are p=0.07088 Ibm/ft?, 0.04615 lbm/fth, and v = 1.809x104 ft /s. Solution: Your solution steps: (15 Marks) Step 1: Assumptions Step 2; Properties Step 3: Solution Your Answer: (10 Marks) Diameter: .......(inset your answer here) (10 Marks)
