1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
Q21 ⇒ In the design of a bag filter, the gas temperature is an important consideration, as it affects the all (a), (b) & (c) [other wrong options] [Discuss in forum] gas density gas viscosity fibre selection |
Q22 ⇒ Hazards associated with the relief valve leakage for extremely hazardous material storage can be taken care of by providing rupture diaphragm [other wrong options] [Discuss in forum] dikes surge chamber none of these |
Q23 ⇒ Shortest distance between two tubes is called tube clearance. [other wrong options] [Discuss in forum] called tube pitch. more in case of triangular pitch as compared to square pitch of tube layout. none of these. |
Q24 ⇒ In a shell and tube heat exchanger, the shortest centre to centre distance between the adjacent tubes is called tube pitch. [other wrong options] [Discuss in forum] called tube clearance. always less than the diameter of the tube. none of these. |
Q25 ⇒ Seamless pipe is made both (b) and (c). [other wrong options] [Discuss in forum] from rolled strips formed into cylinders and seam-welded. by extrusion & casting into static and centrifugal molds. by forging a solid round, piercing it by simultaneously rotating & forcing it over a piercer point and further reducing it by rolling gas drawing. |
Q26 ⇒ Large process vessels operating under extreme temperature and pressure conditions are normally clad/ lined with materials like stainless steel, aluminium, nickel & its alloys, copper & its alloys and titanium. The cladding thickness is generally about __________ percent of the total thickness. 10 to 20 [other wrong options] [Discuss in forum] 1 to 5 30 to 40 40 to 50 |
Q27 ⇒ A/an __________ is used for changing the direction of a pipeline. elbow [other wrong options] [Discuss in forum] union flange disc compensator |
Q28 ⇒ Stress-strain diagram for low carbon steel/mild steel is shown below in the elastic limit [other wrong options] [Discuss in forum] breaking stress ultimate stress yield point |
Q29 ⇒ The shell side pressure drop in a shell and tube heat exchanger is maximum for __________ baffle. orifice [other wrong options] [Discuss in forum] disk and ring segmental independent of the type of |
Q30 ⇒ A pipe is generally made of circular cross-section, because a circular cross-section has the both (a) & (b). [other wrong options] [Discuss in forum] higher structural strength. lowest surface area requirement for a given volume. none of these. |
Q31 ⇒ Smoker's equation for the calculation of number of equilibrium stages in a continuous binary distillation column is used, when the relative volatility is close to one (e.g., separation of close boiling isomers). [other wrong options] [Discuss in forum] feed is not at its bubble point. number of equilibrium stages in only stripping section is to be calculated. number of equilibrium stages required is likely to be very small. |
Q32 ⇒ Generally, as the length of the liquid path on a tray is increased beyond 5 ft, the overall column efficiency increases [other wrong options] [Discuss in forum] decreases remains same may increase or decrease depending upon the plate spacing |
Q33 ⇒ The safe distance of habitation from a hazardous chemical plant (TLV of its product < 1000 ppm) should be about __________ kms. 25 [other wrong options] [Discuss in forum] 1 5 15 |
Q34 ⇒ In packed towers provided with pall rings liquid redistributors are positioned at heights of every 6 metres or 5-10 times the column diameter, whichever is less. Maximum size of the pall rings should not exceed __________ of the column diameter. 1/10-1/15th [other wrong options] [Discuss in forum] 1/5-1/10th 1/20-1/30th 1/2 to 1/4th |
Q35 ⇒ Diameter of rivet hole (d, mm) and the plate thickness (t, mm) are related by Unwin's formula as d = 1.6 t [other wrong options] [Discuss in forum] d = 1.1 t d = 1.5 t 3t |
Q36 ⇒ Which of the following is the most common type of baffle used in industrial shell and tube heat exchanger ? 25% cut segmental baffle. [other wrong options] [Discuss in forum] 75% cut segmental baffle. Orifice baffle. Disk and doughnut baffle. |
Q37 ⇒ Most of the storage vessels/tanks are made cylindrical, because of the fact that a cylinder both (a) and (b). [other wrong options] [Discuss in forum] has greater structural strength. is easy to fabricate. neither (a) nor (b). |
Q38 ⇒ __________ of water makes it a widely used coolant in heat exchangers. High specific heat [other wrong options] [Discuss in forum] Low corrosiveness Low dirt factor Low viscosity |
