Question

A seamless pipe having a diameter of 600 mm and thickness of 9 mm, contain the fluid under a pressure of 4 MPa, find the longitudinal stress developed in the pipe.

• A. 77.7 Mpa
• B. 88.8 Mpa
• C. 66.6 Mpa
• D. 133.3 Mpa

Answer 1

Answer:

C. 66.6 Mpa

Given: p = 4MPa t = 9 mm and d = 600mm Longitudinal stress $\sigma_{l} = \frac{Pd}{4t} \Rightarrow \sigma_{l} =\frac{4 \times 600}{4 \times 9} = 66.66MPa$
