ANS:E - 52431

"Handover the charge to him."

ANS:A - 1

Step 1: int a[3][4] = {1, 2, 3, 4, 4, 3, 2, 8, 7, 8, 9, 0}; The variable a is declared as an multidimensional integer array with size of 3 rows 4 columns. Step 2: int *ptr; The *ptr is a integer pointer variable. Step 3: ptr = &a[0][0]; Here we are assigning the base address of the array a to the pointer variable *ptr. Step 4: fun(&ptr); Now, the &ptr contains the base address of array a. Step 4: Inside the function fun(&ptr); The printf('%d\n', **p); prints the value '1'. because the *p contains the base address or the first element memory address of the array a (ie. a[0]) **p contains the value of *p memory location (ie. a[0]=1). Hence the output of the program is '1'

ANS:E - All the above.

all are correct.  bulking sand increases up to 2-3% only then it became saturated.

And bulking increases with increase in the fine content  more than 10% bulking decreases. C option is incorrect because Bulking of sand more in 5% (4-6%) after then increases moisture decreased the volume. Buckling decreases with a Moisture content of more than 5%.

ANS:B - IL^-2

Current density = current/area = IL^-2.

ANS:C - The operating line lies above the equilibrium curve in case of a gas desorber.

The wrong statement is: "The operating line lies above the equilibrium curve in case of a gas desorber." In a gas desorber, also known as a stripper or regenerator, the operating line lies below the equilibrium curve. This is because a gas desorber is designed to remove solute components from a liquid phase by contacting it with a gas phase. As the solute is transferred from the liquid phase to the gas phase, the concentration of the solute in the liquid decreases, causing the operating line to move below the equilibrium curve. Therefore, the correct statement should be: "The operating line lies below the equilibrium curve in case of a gas desorber."

ANS:B - V₂ > V₁ and V₂ > V₃

For flow through a venturi tube at a particular discharge, the correct relationships among velocities at points X, Y, and Z are typically: V1 > V2 > V3

Explanation:

1. Venturi Tube:
   • A venturi tube is a device used to measure fluid flow by creating a pressure differential between its throat (point Y) and the entrance (point X).
   • The velocity of the fluid varies along the length of the venturi tube due to changes in cross-sectional area.
2. Velocities at Points X, Y, and Z:
   • Point X: Velocity is highest at the entrance (point X) where the cross-sectional area is largest, according to the principle of continuity.
   • Point Y (Throat): Velocity decreases at the throat (point Y) where the cross-sectional area is smallest. This is where the velocity is maximized due to the principle of conservation of mass and Bernoulli's principle.
   • Point Z: Velocity increases again after the throat (point Z) as the cross-sectional area expands, but it remains less than the velocity at point X.
3. Relationship:
   • At a particular discharge rate, the velocity at point X (entrance) is greater than the velocity at point Y (throat), and the velocity at point Y (throat) is greater than the velocity at point Z (exit).
   • Therefore, the correct relationship among velocities at points X, Y, and Z in a venturi tube is typically V1 > V2 > V3, where V1 represents velocity at point X, V2 at point Y, and V3 at point Z.
