ANS:B - 15432

"I want my salary immediately."

ANS:C - The program may crash if some important data gets overwritten.

If the index of the array size is exceeded, the program will crash. Hence "option c" is the correct answer. But the modern compilers will take care of this kind of errors. Example: Run the below program, it will crash in Windows (TurboC Compiler)

#include<stdio.h>

int main()
{
    int arr[2];
    arr[3]=10;
    printf("%d",arr[3]);
    return 0;
}

ANS:A - copper and zinc

No answer description is available.

ANS:B - -15 x 10^-6

.

ANS:D - both (b) and (c).

The critical moisture content during the drying of a solid typically increases with increased thickness of the solid and decreased drying rate. Here's why:

1. Increased Thickness of the Solid: When the thickness of the solid increases, the distance that moisture must travel to reach the surface also increases. This results in a longer diffusion path for moisture to migrate from the interior of the solid to the surface for evaporation. As a result, more moisture needs to be absorbed by the solid before it reaches the critical moisture content required for drying to occur. Therefore, an increased thickness of the solid leads to a higher critical moisture content.
2. Decreased Drying Rate: The drying rate is influenced by factors such as temperature, airflow, and humidity. A decreased drying rate means that the rate of moisture removal from the solid is slower. In this scenario, the solid is exposed to drying conditions for a longer period of time before reaching the critical moisture content. As a result, the solid must absorb more moisture before drying can occur, leading to a higher critical moisture content.

ANS:A - pipe length.

The discharge coefficient (CdC_dCd​) for an orifice meter is primarily influenced by the ratio of pipe diameter to orifice diameter, the type of orifice, and the Reynolds number. Therefore, the correct statement from the options provided is: pipe diameter.

Explanation:

1. Discharge Coefficient (CdC_dCd​):
   • The discharge coefficient (CdC_dCd​) is a dimensionless factor that relates the actual flow rate through the orifice meter to the theoretical flow rate based on the orifice area and the pressure drop across the orifice.
   • It accounts for the effects of fluid velocity profile, frictional losses, and other factors that affect the actual flow through the orifice.
2. Factors Affecting CdC_dCd​:
   • Ratio of Pipe Diameter to Orifice Diameter: This ratio affects the velocity profile and flow conditions upstream and downstream of the orifice, influencing CdC_dCd​.
   • Type of Orifice & Reynolds Number: Different types of orifices (such as sharp-edged, beveled, or venturi) and Reynolds number (flow regime) affect the flow characteristics and thus CdC_dCd​.
   • Pipe Diameter: The pipe diameter itself does not directly influence CdC_dCd​. CdC_dCd​ is primarily determined by the orifice and flow conditions rather than the size of the pipe through which the fluid is flowing.
3. Other Considerations:
   • Pipe Length: The length of the pipe downstream of the orifice can affect pressure recovery and flow characteristics but does not directly influence CdC_dCd​.
   • Type of Orifice & Reynolds Number: These factors are crucial in determining CdC_dCd​ as they impact the flow pattern, turbulence, and pressure drop across the orifice.
