Problem 4 (20 Marks): A very large tank contains air at 102 kPa at a location where the atmospheric air is at 100 kPa and 20C. Now a 2- cm-diameter tap is opened. Determine the maximum flow rate of air through the hole. What would your response be if air is discharged through a 2-m-long, 4-cm-diameter tube with a 2- cm-diameter nozzle? Would you solve the problem the same way if the pressure in the storage tank were 300 kPa? The gas constant of air is R=0.287 kPa.m3/kg.K. 100 kPa 20C 2 cm Air 102 kPa 2 cm 114 cm Solution: Your solution steps: (10 Marks) Step 1: Assumptions Step 2: Properties Step 3: Solution Your Answer: (10 Marks) Maximum flow rate: .......(inset your answer here) (5 Marks) Part b: .......(inset your answer here) (2.5 Marks) Part c: .......(inset your answer here) (2.5 Marks)
