Sample ME6604 important questions:

1. Distinguish between compressible fluid and incompressible fluid flow. (Nov/ Dec- 2006)

Ans: Density is constant for incompressible fluid flow and it is variable for
incompressible fluid flow. The compressibility factor is one for incompressible fluid and is less than one for compressible fluid. Examples are incompressible fluid – water, oil and compressible fluid – air, hydrogen.

2. Define velocity of sound. What is the velocity of sound in air at 27oC? (May 2009)

Ans: The velocity of sound is defined as the velocity at which pressure waves are transmitted through the medium. The velocity of sound in air is calculated by a RT .

3. Define Mach number. (Apr/May- 2008)

Ans: Mach number is defined as the ratio of local velocity of fluid to local sonic velocity at the same point.

4. Define stagnation state and stagnation enthalpy. (Nov/Dec-2009)

Ans: The stagnation state of a fluid is defined as the state of the fluid attained, when the flow is isentropically decelerated to zero velocity at zero elevation. Stagnation enthalpy of a gas is its enthalpy when it is isentropically decelerated to zero velocity at zero elevation.

5. What is the difference between nozzle and diffuser?

Ans: Nozzle is a device in which there is an increase in the velocity and decrease in the pressure. Diffuser is a device which there is a decrease in the velocity and increase in the pressure.

The cylinder may wear out after frequent use. Hence the cylinders have to be replaced, but this is very costly. Therefore, instead of replacing the complete cylinder it is better tofit a parallel sleeve in the block. This sleeve is known as cylinder liner. They are made of
special alloy iron containing manganese, nickel and chromium.

Sample CE6602 Important questions:

1. Whatis meantby indeterminatestructures?

Structures that do not satisfy the conditions of equilibrium are called indeterminate structure. These structures cannot be solved by ordinary analysis techniques.

4. Define degree of indeterminacy

(i). The excess number of reaction is that make a structure indeterminate is called degree of
indeterminacy,and is denoted by(i).Indeterminacy is also called degree of redundancy. Indeterminacy consists of internal and external in determinacies.

CE6601 important questions DESIGN OF REINFORCED CONCRETE and BRICK MASONRY STRUCTURES

CE6601 important questions DESIGN OF REINFORCED CONCRETE and BRICK MASONRY STRUCTURES Regulation 2013 Anna University free download. DESIGN OF REINFORCED CONCRETE and BRICK MASONRY STRUCTURES important questions pdf free download.

Sample CE6601 important questions:

1. What is a Retaining wall?

Retaining walls are generally used to retain earth or such materials to maintain unequal levels on its two faces. The soil on the back face is at a higher level and is called back fill. Retaining walls are extensively used in the construction of basements below ground
level, wing walls of bridge and to retain slopes in hilly terrain roads.

2. What are the disadvantages of gravity retaining walls?

Gravity walls of stone masonry were generally used in the earlier days to the height of the earth fill. The advent of reinforced concrete has resulted in thinner retaining walls.

3. What are the types of retaining walls?

Retaining wall can be classified structurally as
1. Cantilever retaining wall
2. Counter fort retaining wall

4. What is a cantilever retaining wall?

The most common and widely used retaining wall is of cantilever type. Vertical stem resisting earth pressure one side and the slab bends like a cantilever. The thickness of the vertical slab is large at the bottom and decreases towards the top in proportion to the varying soil pressure.

5. What is a counter fort retaining wall?

Counter fort retaining walls are used for large heights exceeding 5 mts of earth fill. In counter fort retaining wall the vertical stem is designed as a continuous slab spanning between the counter forts. Counter forts are designed as cantilever beams from the base slab.
