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) Σ/E Σ E/σ E Σ/E Σ E/σ E ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir length for a bubble cap plate is the same as that for the seive plate Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate Weir height for a bubble cap plate column is the same as that for a seive plate column The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir length for a bubble cap plate is the same as that for the seive plate Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate Weir height for a bubble cap plate column is the same as that for a seive plate column ANSWER DOWNLOAD EXAMIANS APP
