Process Equipment and Plant Design In a shell and tube heat exchanger for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes None of these Are less prone to fouling Are easier to clean Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less None of these Are less prone to fouling Are easier to clean Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less ANSWER DOWNLOAD EXAMIANS APP
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 E/σ Σ E Σ/E E/σ Σ ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Smaller sized packings are generally dumped to the packed columns, and the large ones of size greater than __________ mm are stacked individually, which provides better control over bed porosity and offers lower gas pressure drop. 50 150 75 25 50 150 75 25 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design A perforated plate has holes of diameter dh arranged in a pitch ph. Each hole has a tube of I.D. dt passing through it.
