Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): Depth of centre of pressure of any immersed surface is independent of the density of the liquid. Statement (II): Centre of area of the immersed body lies below the centre of pressure.

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): In flow through a pipeline, the nature of the fluid flow depends on the velocity of the fluid. Statement (II): Reynolds number of the depends on the velocity, the diameter of the pipe and the kinematic viscosity of the fluid.

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): The specific heat at constant pressure for an ideal gas is always greater than the specific heat at constant volume. Statement (II): Heat added at constant volume is not utilized for doing any external work.

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): A homogeneous mixture of gases that do not react within themselves can be treated as a pure substance. Statement (II): Flue gases can be treated as a homogeneous mixture of gases.

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): Air-blast injection in diesel engines could reduce engine efficiency. Statement (II): Air-blast injection in diesel engines is not instantaneous but happens when the piston moves outward with the injection valve remaining open for whatever reason.

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): Use of non-azeotropic mixtures used as the refrigerant in a vapour compression system improves the coefficient of performance. Statement (II): The increase in this coefficient is attributable to reduction in volume.
