A very large tank contains air at 102 kPa at a location where the atmospheric air is at 100 kPa and 20°C. 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?

A very large tank contains air at 102 kPa at a location
where the atmospheric air is at 100 kPa and 20°C. 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?
