A horizontal cylinder of internal diameter 100mm is filled with water & rotated about axis with an angular velocity 3000rpm.calculate the pressure at the ends of the horizontal & vertical diameter.?

Question

Answer

To find the volume of water in the cylinder, we need to first calculate the cross-sectional area of the cylinder.

The internal diameter of the cylinder is given as 100mm, which means the radius (r) is half of that, or 50mm. To convert the radius to meters, we divide by 1000:

r = 50mm / 1000 = 0.05m

The cross-sectional area of the cylinder (A) can be calculated using the formula for the area of a circle:

A = πr^2

A = π(0.05m)^2

A = 0.00785 m^2

Now, we need to find the height (h) of the water in the cylinder. Since the cylinder is horizontal, the height of the water will be the same as the length of the cylinder.

Let's assume the length of the cylinder is L.

The volume of water in the cylinder (V) is given by the formula:

V = A * L

We can rearrange this formula to solve for L:

L = V / A

However, we don't have the volume of water or the length of the cylinder, so we cannot calculate the height of the water without additional information.
