In the formula (TS x t x E) / (R x FS), what does 'R' stand for?

Radius of the tank
Inside radius of weakest course of shell or drum
Resistance of the material
Rate of flow

The correct answer is: Inside radius of weakest course of shell or drum

In the given formula (TS x t x E) / (R x FS), 'R' represents the inside radius of the weakest course of the shell or drum. This component is critically important in the context of boiler design and operation, as it directly relates to the structural integrity and safety of the vessel. When calculating the allowable working pressure of a boiler, the inside radius is vital for determining the stresses experienced by the walls under operational conditions. The weak point, or the weakest course, is essential because it dictates the maximum pressure that the boiler can safely handle. By using the inside radius at this vulnerable point, the formula ensures that the calculations account for potential failures in the structure, thereby enhancing safety and reliability. Understanding this aspect helps operators and engineers ensure that the design and operation of boilers comply with safety regulations and standards, which is crucial in preventing accidents and maximizing efficiency.
