Re: BHEL Exam Question Paper
Here is the list of few questions of BHEL Exam question paper which you are looking for . 1)Unit of Entropy (J/kg K or kJ/kg K) 2)A mass of 100kg is falling from a height of 1 m and penetrates the sand into for 1 m. What is the resistance force given by sand. 3)Ratio of specific heats of air. (1.41) 4)A body weighs 3 kg in air. If it is submerged in a liquid, it weighs 2.5 kg. What is the specific gravity of the liquid. 5)Two cars travell in same direction at 40 km/hr at a regular distance. A car comes in a opposite direction in 60km/hr. It meets each car in a gap of 8 seconds. What is the distance between them? 6)A simple problem involing in hoops stress. For sphere: M= [3/2]*p*V*[density of pressure vessel material/Maximum working stress it can tolerate] For Thin walled pressure walls: Hoops stress or stress in the radial direction =p*r/2t 7)A problem in force calculation in a body moving in a inclined surface. 8)Composition of bronze. (Copper+zinc) 9)Compostion of stainless steel.(iron+chromium+nickel+carbon) 10)CI is manifactured in which process. (cupola process) 11)What percentage of carbon is preset in pig iron. (4.5 to 6%) 12)Water is available at 10m height. What is the pressure available? (pressure=density*g*height; p=1000*9.81*10; p=98100N/m2) 13)What will happen if the speed of the centrifugal pump doubles. 14)The unit eV is widely used in ? (Nuclear and atomic physics) 15)What will happen to the resistance, when the diameter of the conductor is doubled? 16)The power comsumed by a electrical device is 1000W at 250V, What is the resistance in the device? (Power= Voltage*current; Current=Power/Voltage, Current,I=1000/250=4 amps. V=IR, Therefore R=250/4=62.5 ohms) 17)Why DC current is not used in transformer. 18)On what principle the sonar/ radar( I dont remember) works? 19)Bending moment diagram for the UDL is in what shape? 20)Function of the distributor in petrol vehicles? (Spark timing) |
