Time and time related variables in engineering

Time is the event progression starting from past to present and then, future statistically. The time-related variable is any particular value in relation to time to assess its changes on a specified (XY) plane.

Question

The following data for an exploration well of 13,000 ft depth:
Hole diameter = 8.1/2 inch
Hole depth = 13,000 ft
Plastic viscosity = 35 cP
Yield point = 25 lb / 100 ft²
Mud weight = 13 lb / gal
Flow rate = 400 gpm
Drill pipe ID = 4.276 in / OD = 5 in
Drill collars ID = 2.875 in / OD = 6.5 in / Length = 500 ft
Previous casing = 95/8 in / ID = 8.755 in set at 10,000 ft
Pump pressure = 3000 psi
Surface equipment type = 4

Full Detailed Explanation and Solution please Thank you much
Styles Editin A production casing was planned to run in the production hole of a well with casing shoe at 15,000 ft. When casing was run empty to the mid depth, collapse safety factor was calculated to be 1.9. When the casing was at the bottom and full of a certain mud, safety factor of the collapse was calculated to be 2.75. If the mud weight of the fluid in the annulus was 14.0 ppg, determine the casing collapse rating and mud weight of the fluid inside the casing.
