2. A cast iron pipe is to carry 60 m³ of compressed air per minute at a pressure of 1 N/mm². The velocity
of air in the pipe is limited to 10 m/s and the permissible tensile stress for the material of the pipe is
14 MPa. Find the diameter of the pipe and its wall thickness.
[Ans. 360 mm; 22 mm]
3. A seamless steel pipe carries 2000 m³ of steam per hour at a pressure of 1.2 N/mm². The velocity of
flow is 28 m/s. Assuming the tensile stress as 40 MPa, find the inside diameter of the pipe and its wall
thickness.
[Ans. 160 mm; 5.4 mm]
