Question

A stream boiler of 800 mm diameter is made up of 10 mm thick plates. If the boiler is subjected to an internal pressure of 2.5 MPA, find the circumferential & longitudinal stress induced in the boiler plate.​

Answer 1

Step-by-step explanation:

Given: Diameter of boiler (d) = 800 mm Thickness of plates (t) = 10 mm internal pressure (p) = 2.5 MPa = 2.5 N/mm2 . Circumferential stress induced in the boiler plates We know that circumferential stress induced in the boiler plates σ c = pd 2 t = 2.5 × 800 2 × 10 = 100 N / mm 2 = 100 MPa .
