In the formula (TS x t x E) / (R x FS), 'E' represents the efficiency of the longitudinal joint. This term is commonly used in calculations involving the strength and effectiveness of a longitudinal joint in pressure vessels or piping systems. The efficiency of the joint is crucial because it affects the overall reliability and pressure-holding capability of systems that use welded or bolted connections.

Understanding the factors in this formula is important, especially in boiler operations where the integrity of joints can impact safety and performance. If the efficiency of the joint is not adequately accounted for, it can lead to failures, leaks, or even catastrophic incidents in pressurized systems. Recognizing the role of 'E' helps in ensuring that proper safety standards and engineering practices are maintained, contributing to the overall effectiveness and safety of boiler systems in operation.

The other options, while relevant in different contexts, do not fit the specific meaning of 'E' within this formula used in boiler operations.
