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 ⇒ Thermal conductivity cell is the primary element of a/an __________ analyser. carbon dioxide [other wrong options] [Discuss in forum] oxygen carbon monoxide sulphur dioxide |
Q22 ⇒ Meleoid gauge measures the __________ pressure. sub-atmospheric [other wrong options] [Discuss in forum] positive very high atmospheric |
Q23 ⇒ Which of the following fluid flow measuring devices can measure the largest flow rate ? Weir [other wrong options] [Discuss in forum] V-notch Rotameter Orificemeter |
Q24 ⇒ Which of the following is not a composition measuring instrument ? Hot wire anemometer [other wrong options] [Discuss in forum] Thermal conductivity cell Mass spectrometer Polarograph |
Q25 ⇒ Which of the following flow-metering instru-ments is an areameter ? Rotameter [other wrong options] [Discuss in forum] Venturimeter Pitot tube Hot wire anemometer |
Q26 ⇒ A control system has the following transfer func 1 [other wrong options] [Discuss in forum] 42743 42924 -1 |
Q27 ⇒ Which of the following thermocouples has the widest temperature measurement range ? Platinum-platinum/rhodium [other wrong options] [Discuss in forum] Iron-constantan Chromel-alumel Copper-constantan |
Q28 ⇒ Pick out the wrong statement. Transfer lag decreases as the number of stages decreases. [other wrong options] [Discuss in forum] There is no transfer lag for a single first order system. Stirred tank with a water jacket exemplifies an interacting system. Transfer lag is a characteristics of all higher order systems (other than first order systems). |
Q29 ⇒ Thermocouple is suitable for measuring both high and low temperatures. [other wrong options] [Discuss in forum] liquid temperatures only. very high temperatures only. very low temperatures only. |
Q30 ⇒ Temperature of __________ can not be measured by an optical or radiation pyrometer. hot blast (air) from stoves [other wrong options] [Discuss in forum] molten slag flowing out of blast furnace combustion space in boilers rotary limestone calcination kiln |
Q31 ⇒ __________ is an example of distributed parameter system Tubular reactor [other wrong options] [Discuss in forum] CSTR On-off controller none of these |
Q32 ⇒ The unit of 'time constant' of a system is the same as that of time [other wrong options] [Discuss in forum] velocity (time)-1 none of these |
Q33 ⇒ The Laplace transform of exp(at), where a > 0, is defined only for the Laplace parameter, s > a since the Laplace transform of integral of exp(at) has finite values only for s > a. [other wrong options] [Discuss in forum] the function is exponential. the Laplace transform integral of exp(at) has initial values only for s > a. the function exp(at) is piece-wise continuous only for s > a. |
Q34 ⇒ Change of angle of refraction with composition comprises the working principle of a refractrometer [other wrong options] [Discuss in forum] polarimeter polarograph spectrometer |
Q35 ⇒ 0n-off control which is a special case of proportional control, has a band width of about __________ percent. 0 [other wrong options] [Discuss in forum] 100 75 25 |
Q36 ⇒ In second order underdamped system, decay ratio = (overshoot)2 [other wrong options] [Discuss in forum] decay ratio = overshoot overshoot increases for increasing damping co-efficient. large damping co-efficient means smaller damping. |
Q37 ⇒ If response of a control system is to be free of offset and oscillation, the most suitable controller is proportional integral-derivative (PID) controller. [other wrong options] [Discuss in forum] proportional controller. proportional-derivative(PD)controller. proportional-integral (PI) controller. |
Q38 ⇒ For two non-interacting first order systems connected in series, the overall transfer function is the __________ of the individual transfer functions. product [other wrong options] [Discuss in forum] ratio sum difference |
Q39 ⇒ Load cells are used for the measurement of weight [other wrong options] [Discuss in forum] stress strain velocity |
Q40 ⇒ Which of the following relates the emf. generated in a single homogeneous wire to the temperature difference ? Thomson effect [other wrong options] [Discuss in forum] Peltier effect Seebeck effect none of these |
