ANS:A - True

Yes, It is possible to allocate a block of memory (of arbitrary size) at run-time, using the standard library's malloc function, and treat it as an array.

ANS:C - to avoid long offsets from chain lines

Main line:line joining two main survey stations.
Tie line is used for surveying detail.
Check line is used for checking the work.
Base line :longest chain line. Tie line is mainly used for the joining of subsidiary lines or two offset lines. Check lines are used to check the accuracy of the work. The offset having their length more than 15m is called long offset so avoid the long offset to reduce error in chain lines. Tie or subsidiary lines: A tie line joints two fixed points on the main survey lines. It helps to checking the accuracy of surveying and to locate the interior details. Tie line is the line used to join survey line to features to avoid long offsets. It is used to check for accuracy on chain lines.

ANS:C - surface evaporation of unbound moisture occurs.

"Surface evaporation of unbound moisture" refers to the process by which moisture present on the surface of a solid material evaporates into the surrounding air when the solid is exposed to suitable drying conditions. This phenomenon typically occurs during the latter stages of the drying process, specifically during the falling rate period. Here's a breakdown of the process:

1. Unbound moisture: Unbound moisture refers to the moisture present on the surface of the solid material that is not chemically or physically bound to the solid structure. This moisture is relatively easy to remove and is typically the first to evaporate during the drying process.
2. Surface evaporation: As the solid material loses moisture during the drying process, the concentration of moisture at the surface decreases. When the moisture concentration at the surface is higher than the equilibrium moisture content corresponding to the surrounding air conditions (e.g., temperature, humidity), evaporation occurs.
3. Falling rate period: Surface evaporation of unbound moisture is most prominent during the falling rate period of drying. In this stage, the drying rate gradually decreases as the moisture content of the solid decreases and approaches equilibrium with the drying conditions. During this period, the rate of moisture removal is limited by factors such as diffusion of moisture from the interior of the solid to the surface.
4. Drying conditions: Surface evaporation of unbound moisture depends on the drying conditions, including temperature, humidity, and airflow. Higher temperatures and lower relative humidity levels enhance evaporation rates by increasing the vapor pressure difference between the solid surface and the surrounding air.

ANS:A - butterfly valve

The most economical flow control valve for use with large diameter pipes is a butterfly valve.

Explanation:

1. Butterfly Valve:
   • A butterfly valve is a type of quarter-turn valve that controls flow by rotating a disc (or "butterfly") in the fluid path.
   • It is well-suited for large diameter pipes because it requires less material and is lighter compared to other types of valves, such as globe valves or gate valves.
   • The reduced material and weight contribute to lower manufacturing costs and easier installation.
2. Advantages for Large Diameter Pipes:
   • Cost-Effective: Butterfly valves are generally less expensive to manufacture and install compared to globe valves or gate valves.
   • Low Pressure Drop: They have a low pressure drop across the valve, which minimizes energy losses in large diameter pipelines.
   • Maintenance: Butterfly valves are relatively easy to maintain and operate due to their simple design and fewer moving parts.
3. Other Valve Types:
   • Globe Valve: Globe valves are better suited for throttling and controlling flow where precise regulation is required, but they are generally more expensive and have higher pressure drops compared to butterfly valves.
   • Needle Valve: Needle valves are used for fine control of flow, typically in small diameter pipes or for precise applications, and are not typically economical for large diameter pipes.
4. Conclusion:
   • Butterfly Valve: Given its simplicity, lower cost, and suitability for large diameter pipes, a butterfly valve is considered the most economical choice for flow control in such applications. It strikes a balance between cost-effectiveness and efficient flow regulation in industrial and large-scale piping systems.
