Process Equipment and Plant Design Elastic failure of a material occurs, when the tensile stress equals yield strength, yield point or the elastic limit. Also, the elastic failure occurs according to maximum strain theory, when the maximum tensile strain equals (where, σ = yield strength and E = modulus of elasticity) E/σ E Σ Σ/E E/σ E Σ Σ/E ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of the distillation column. Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up If sufficient slot area is not provided, the gas may pass through the skirt clearance The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles None of these Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up If sufficient slot area is not provided, the gas may pass through the skirt clearance The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles None of these ANSWER DOWNLOAD EXAMIANS APP
