A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example 'E' can be represented by 32, 12 etc and 'X' can be represented by 87, 79 etc. Similarly, you have to identify the set for the word 'MYTH'.

Which of the following statements are CORRECT?
I. Ionic compounds have high melting and boiling points.
II. Carbon compounds are poor conductor of electricity.
III. Carbon compounds have low melting and boiling point.

What is the length of a belt with diameter $$d_1$$ and $$d_2$$ and at distance x apart, is connected by means of an open belt drive?

What does the term jump signifies in cam and follower?

What is the normal stress on a bar of square cross- section with side ‘b’ on which load P is applied at an angle of 30o from the horizontal?

A steel rod whose diameter is 6 cm and is 1 m long, experiences heating from temperature $$40^\circ C$$ to $$200^\circ C$$. The coefficient of thermal expansion is $$\alpha = 12 \times 10^{-8} / ^\circ C$$ and Young's modulus is 300 GPa. If the rod has not been restricted in its original position, the thermal stress (MPa) developed is ..............

Which of the following statement is TRUE for sudden loading?

Which of the following is NOT a feature of Carnot engine?

Which of the following statement is FALSE about entropy?

What will be the change in the level of water when the closed and rigid tank of volume 0.035 m$$^3$$ is slowly heated. The mass of the mixture is 10 kg at 0.1 MPa and water has a critical specific volume of 0.004155 m$$^3$$/kg?

A Carnot engine operates between temperature 1000 K and 400 K. The heat rejected by the first Carnot engine is used by the second Carnot engine, whose sink temperature is 200 K. If the net heat absorbed by the first Carnot engine is 200 MJ. What is the heat rejected (in MJ) by the second Carnot engine?

An engine based on a standard Otto cycle is operating with air as an medium with specific heat of 1.4 has a cylinder diameter of 5 cm and stroke length of 7.5 cm. If the clearance volume is 88.15 cc and the heat supplied per kg of air per cycle is 900 kJ/kg, then work output (in kJ) per kg of air is?

A closed system contains saturated liquid ammonia at $$10^\circ C$$. The mass of ammonia is 5 kg. The amount of heat that is required to convert all thesaturated liquid to vapour at constant pressure is 16.2 MJ. If the entropy of saturated liquid is 0.88 kJ/kg-K, what is the entropy (kJ/kg-K) of saturated vapour process without heat transfer?

The continuity equation

The general equation of continuity for three-dimensional flow of a compressible fluid for steady flow is (u, v, w, are components of velocity in x, y and z direction).

If u, v, w are the components of the velocity v of a moving particle, then the equation $$\frac{u}{dx} = \frac{v}{dy} = \frac{w}{dz}$$ represents an equation of

If $$l_1, l_2, l_3$$ etc. be the lengths and $$d_1, d_2, d_3$$ etc. be the diameters of the parts of a compound pipe, then length L and diameter D of a uniform equivalent pipe will be related as under
