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)
