Oil Filled Tanks - Heat Loss

Heat loss from insulated and uninsulated, sheltered and exposed heated oil tanks. Calculate heat transfer rates and total heat loss using the formula Q = α A dt.

Tank Temperature (°C)	Tank Temperature (°F)	Uninsulated W/(m² °C)	Uninsulated Btu/(hr ft² °F)	Insulated W/(m² °C)	Insulated Btu/(hr ft² °F)
10	50	6.8	1.2	1.7	0.3
27	80	7.4	1.3	1.8	0.33
38	100	8	1.4	2	0.35

Tank Temperature (°C)	Tank Temperature (°F)	Uninsulated W/(m² °C)	Uninsulated Btu/(hr ft² °F)	Insulated W/(m² °C)	Insulated Btu/(hr ft² °F)
