There  is a storage tank with specified internal diameter and height.(  crude oil storage tank ) How can I calculate liquid levels in this tank? ( low- low  - low - high and high-high)

The liquid levels in a storage tank are normally calculated by liquid flow rate and residence time required inside the storage tank. High high liquid level is normally determined by process reasons or equipment protection. When the liquid level is over High high, there may be liquid carryover, liquid overflow, liquid entrainment, etc. 

 

When the liquid level is below low low, there may be pump cavitation, gas escaping from the liquid draw line, etc.

 

For the volume between the low low and high high, it is normally determined by surging time required for stable operation.

 

Hope this help
