Can be estimated with values from the table above as. The intersection of line a with scale 3 is the tank volume approximately 17 000 gallons. Calculate the heat loss from the storage tank using the formula q α x a x dt where q is the heat loss in btu hr α is the heat transfer rate in btu hr ft 2 f a is the surface area in square feet and dt is the temperature difference of the tank fluid and ambient temperature. Example heat loss from an open water tank.

This is calculated to be 0 4 x 302 x 90 30 or 7 248 btu hr of. This is calculated to be 0 4 x 302 x 90 30 or 7 248 btu hr of. A high grade 90 10 cupronickel heat exchanger coil restores full water. The heat loss from an open water tank with.

Hot water in the stainless steel storage tank stays hot longer because there s no flue heat loss plus the tank is protected by a two inch blanket of thermal foam insulation. Tank 12 diameter by 20 long. Q evaporation fluid radiation fluid 1040 btu ft 2 hr 10 ft 2 10400 btu hr. Insulated pipes heat loss diagrams.

Our thermex stainless steel hot water tanks are pressure tested to a full 12 bar four times their normal working pressure and injected with 50mm of our hcfc free polyurethane insulation to achieve astonishingly low levels of heat loss which maximises energy efficiency for your customers. Connect 12 on scale 2 with 20 on scale 6 line a. Un insulated bare steel tank walls area. Heat loss w ft diagrams for insulated pipes ranging 1 2 6 inches insulation thickness 0 5 4 inches temperature difference 50 350 deg f.

Temperature limits for some commonly used insulation materials. Chart is based upon still air. Calculate the heat loss from the storage tank using the formula q α x a x dt where q is the heat loss in btu hr α is the heat transfer rate in btu hr ft 2 f a is the surface area in square feet and dt is the temperature difference of the tank fluid and ambient temperature. The intersection of this line with scale 4 is the surface area of the cylindrical portion of the tank approximately 800 sq.

The heat loss due to evaporation of water from a surface of an open tank is dominant at higher water temperatures. Insulation materials temperature ranges.
