Here three cases must be investigated:

(a) circumferential stress due to internal pressure

(b) longitudinal tensile stress due to bending must be added to the longitudinal stress due to

(c) Longitudinal compressive stress due to bending.

Case 1 circumferential tensile stress. In this horizontal vessel; the equation in UG-27 (c)(1) is used:

P = 0.65 + gH/106 = 0.65 + 10009.816.769/106 = 0.7165 MPa
