In an oil refinery, cylindrical tanks of 20 m diameter and 15 m height are used to store crude oil. A process technician notes down the following data on a particular tank:
Time: 8:00 am
Oil level in the tank: 7.0 m
Flowmeter reading at the tank inlet: 7430 liters/min
Flowmeter reading at the tank outlet: 305 m^3/hour
Assuming the flow rates remain steady,
a. Estimate the oil level in the tank at 10:00 am
b. When will the tank reach maximum capacity?
