Mean Surface area of Tube when Heat transfer takes place from outside to inside surface of tube Solution

STEP 0: Pre-Calculation Summary

Formula Used

Surface Area = (Heat Transfer*Tube Thickness)/(Thermal Conductivity*(Outside Surface Temperature-Inside Surface temperature))
SA = (q*x)/(k*(T₂-T₃))
This formula uses 6 Variables

Variables Used

Surface Area - (Measured in Square Meter) - The Surface Area of a three-dimensional shape is the sum of all of the surface areas of each of the sides.
Heat Transfer - (Measured in Watt) - Heat Transfer is the amount of heat that is transferred per unit of time in some material, usually measured in watts (joules per second).
Tube Thickness - (Measured in Meter) - Tube Thickness is the thickness of the tube defined by a gauge number.
Thermal Conductivity - (Measured in Watt per Meter per K) - Thermal Conductivity is rate of heat passes through specified material, expressed as amount of heat flows per unit time through a unit area with a temperature gradient of one degree per unit distance.
Outside Surface Temperature - (Measured in Kelvin) - Outside Surface Temperature is the Temperature at the outside surface of the tube.
Inside Surface temperature - (Measured in Kelvin) - Inside Surface Temperature is the temperature at the inside surface of the tube.

STEP 1: Convert Input(s) to Base Unit

Heat Transfer: 7.54 Watt --> 7.54 Watt No Conversion Required
Tube Thickness: 11233 Millimeter --> 11.233 Meter (Check conversion here)
Thermal Conductivity: 10.18 Watt per Meter per K --> 10.18 Watt per Meter per K No Conversion Required
Outside Surface Temperature: 310 Kelvin --> 310 Kelvin No Conversion Required
Inside Surface temperature: 302 Kelvin --> 302 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SA = (q*x)/(k*(T₂-T₃)) --> (7.54*11.233)/(10.18*(310-302))

Evaluating ... ...

SA = 1.03999042239686

STEP 3: Convert Result to Output's Unit

1.03999042239686 Square Meter --> No Conversion Required

FINAL ANSWER

1.03999042239686 ≈ 1.03999 Square Meter <-- Surface Area

Mean Surface area of Tube when Heat transfer takes place from outside to inside surface of tube Formula

Surface Area = (Heat Transfer*Tube Thickness)/(Thermal Conductivity*(Outside Surface Temperature-Inside Surface temperature))
SA = (q*x)/(k*(T₂-T₃))

Natural convection air-cooled condensers

In natural convection air-cooled condenser, the heat transfer from the condenser coils to the air is by natural convection. As the air comes in contact with the warm condenser tubes, it absorbs heat from the refrigerant, and thus the temperature of the air increases. The warm air, being lighter, rises up and the cold air from below rises to take away the heat from the condenser.

Forced convection air-cooled condensers

In forced convection air-cooled condensers, the fan (either propeller or centrifugal) is used to force the air over the condenser coils to increase its heat transfer capacity. The forced convection condensers may be divided into the following two groups: (a) Base mounted air-cooled condensers, and (b) Remote air-cooled condensers.
