ANS:A - 2, 3, 4, 5
Step 1: void fun(int, int[]); This prototype tells the compiler that the function fun() accepts one integer value and one array as an arguments and does not return anything.
Step 2: int arr[] = {1, 2, 3, 4}; The variable a is declared as an integer array and it is initialized to
a[0] = 1, a[1] = 2, a[2] = 3, a[3] = 4
Step 3: int i; The variable i is declared as an integer type.
Step 4: fun(4, arr); This function does not affect the output of the program. Let's skip this function.
Step 5: for(i=0; i<4; i++) { printf('%d,', arr[i]); } The for loop runs untill the variable i is less than '4' and it prints the each value of array a.
Hence the output of the program is 1,2,3,4

A inversely proportional to 'P'.
B dependent on the molecular volume & molecular weight of components.
C directly proportional to 'T1.5'.
ANS:D - all 'a', 'b' & 'c'.
As per Gilliland's equation, the diffusivity is directly proportional to 'T^1.5' and inversely proportional to 'P'.
Gilliland's equation describes the diffusivity (𝐷D) of a gas mixture and is given by:
𝐷=0.001858𝑇1.5𝑃D=P0.001858T1.5
Where:
- 𝐷D is the diffusivity of the gas mixture.
- 𝑇T is the absolute temperature in Kelvin.
- 𝑃P is the pressure in atm.
According to Gilliland's equation:
- Diffusivity is directly proportional to the square root of temperature raised to the power of 1.5 (𝑇1.5T1.5). This means that as temperature increases, the diffusivity increases.
- Diffusivity is inversely proportional to pressure ('P'). This means that as pressure increases, the diffusivity decreases.
However, Gilliland's equation does not directly account for molecular volume and molecular weight of components. Therefore, the correct answer is directly proportional to 'T^1.5' and inversely proportional to 'P'.

ANS:D - Compressors
Among the options provided, compressors produce the maximum pressure difference for the transportation of gases.
Explanation:
-
Compressors:
- Compressors are devices designed to increase the pressure of a gas by reducing its volume. They are used to create a significant pressure difference between the inlet and outlet.
- Compressors are capable of generating high pressure differentials, making them suitable for applications where gases need to be transported over long distances or at high pressures.
-
Vacuum Pumps:
- Vacuum pumps, on the other hand, are used to create a vacuum or low-pressure environment by removing gases from a sealed chamber. They work in the opposite direction to compressors, reducing pressure rather than increasing it.
-
Blowers and Fans:
- Blowers and fans are also used to move gases, but they typically operate at lower pressure differentials compared to compressors. They are more suited for applications where moderate pressure differences are required, such as ventilation or cooling systems.
-
Maximum Pressure Difference:
- Compressors are specifically designed to handle higher pressure differences, making them the appropriate choice when significant pressure elevation is needed for gas transportation or processing.
Conclusion:
Therefore, compressors are the correct answer as they produce the maximum pressure difference for the transportation of gases among the options provided. They are essential in industries such as oil and gas, chemical processing, and refrigeration, where high-pressure gas handling is required.
