    Describe the purpose of scavenging in IC Engines
  • d
    Explain the parallel type of hybrid electrical vehicle
  • e
    Describe the one ton of refrigeration in SI system
  • f
    Differentiate between dry bulb and wet bulb temperatures
  • g
    Calculate the specific gravity of one liter of a liquid that weighs 7N
  • h
    What is the working principle of an impulse turbine? i. Differentiate between accuracy and precision. j. What is a transducer? Describe with any one example
Section BAttempt any three of the following: 7x3=21
  • a
    Draw the stress-strain curve for mild steel and describe its salient points. Also, draw the stress curve for a ductile material, a brittle material, and a plastic material
  • b
    Discuss any four important components of an IC Engine and the major functions of those components
  • c
    Explain the basic vapor compression cycle and describe the working of a domestic refrigerator
  • d
    Differentiate between the absolute, gage and vacuum pressure. A manometer, shown in figure, is used to measure the pressure of a gas in a tank. The fluid used has a specific gravity of 0.85, and the manometer column height is 55 cm. If the local atmospheric pressure is 96 kPa, determine the absolute pressure within the tank
  • e
    Explain the Seebeck effect and the working principle of thermocouples with help of
  • a
    neat sketch. Also discuss their advantages and disadvantages
Section CAttempt any one part of the following: 7x1=7
  • a
    A system of four forces acting on a body is as shown in figure. Determine the resultant
  • b
    At an axial load of 22 kN, a 45-mm-wide by 15-mm thick polyimide polymer bar elongates 3.0 mm while the bar width contracts 0.25 mm. The bar is 200 mm long. At the 22-kN load, the stress in the polymer bar is less than its proportional limit. Determine
  • 1
    The modulus of elasticity
  • 3
    The change in the bar thickness x.kuk djsaA
  • 1
    Ů̾ (modulus of elasticity )
  • 2
    ik;lu (Poisson’s ratio)
  • a

  • a
    Explain the following terms related to air conditioning: iv. Relative humidity (lkis{k vknzZrk)
  • b
    Define coefficient of performance (COP) for a refrigeration system. Why do we express the performance in terms of COP instead of efficiency? Also, compare the COPs of a refrigerator and a heat pump
  • a
    Explain Pascal’s law with help of a neat sketch. What are its practical applications? The small piston of a hydraulic lift has an area of 0.20 m2. A car weighing 1.2 x 104 N sits on a rack mounted on the large piston. The large piston has an area of 0.90 m2. How large force must be applied to the small piston to support the car
  • b
    Describe the working principle of a reciprocating pump. Why are these pumps called positive displacement pumps?
  • a
    i. Briefly explain a Bourbon tube-based pressure measurement device. ii. Differentiate between bonded and unbonded strain gauges systems
  • b
    i. Differentiate between Autotronics, Bionics, and Avionics along with their applications. ii. Discuss the merits and demerits of mechatronics systems
