Horizontal Tank Partial Fill Calculator
Volume in a part-full horizontal cylindrical tank
Formula: partial_volume = length × (radius² × acos((radius − fill_height)/radius) − (radius − fill_height) × sqrt(2×radius×fill_height − fill_height²))
Calculate the liquid volume in a horizontal cylindrical tank at a given fill height. Use for fuel-tank inventory, water and chemical storage, and milk haulage. Note: for custody-transfer applications, use the tank's calibrated chart instead — this is for operational estimation only.
