Process Equipment and Plant Design The centre to centre distance between two consecutive baffles in a shell and tube heat exchanger is called the baffle pitch or baffle spacing, which is more than 1/5th the I.D. of the shell. Which of the following is not a function of the baffles? To provide support to the tube bundle To increase the tube side heat transfer co-efficient by inducing turbulence To increase the residence time of shell side fluid To reduce the induced vibration in the tubes To provide support to the tube bundle To increase the tube side heat transfer co-efficient by inducing turbulence To increase the residence time of shell side fluid To reduce the induced vibration in the tubes ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Heat transfer co-efficient, hG(Kcal/hr.m² .°C) and mass velocity of air, G (kg/hr.m² ) for air flow parallel to the surface in case of constant drying rate in batch drying is related as hG = 0.0176G0.8. But when the flow of air perpendicular to the surface is encountered, this equation changes to HG = 1.004G0.37 0.0176G1.37 HG = 0.0176G0.37 1.004G0.8 HG = 1.004G0.37 0.0176G1.37 HG = 0.0176G0.37 1.004G0.8 ANSWER DOWNLOAD EXAMIANS APP

Generally, larger the knuckle radius, stronger is the corner torus section of a head. The knuckle radius provided should be less than __________ of the head. 3 times the thickness 6% of I.D. Either A or B, whichever is smaller Either A or B, whichever is larger 3 times the thickness 6% of I.D. Either A or B, whichever is smaller Either A or B, whichever is larger 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 Σ Σ/E E/σ E Σ Σ/E ANSWER DOWNLOAD EXAMIANS APP
