q = (k*SA*(T₂-T₃))/x
This formula uses 6 Variables

Variables Used

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).
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.
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.
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.
Tube Thickness - (Measured in Meter) - Tube Thickness is the thickness of the tube defined by a gauge number.

STEP 1: Convert Input(s) to Base Unit

Thermal Conductivity: 10.18 Watt per Meter per K --> 10.18 Watt per Meter per K No Conversion Required
Surface Area: 1.04 Square Meter --> 1.04 Square Meter No Conversion Required
Outside Surface Temperature: 310 Kelvin --> 310 Kelvin No Conversion Required
Inside Surface temperature: 302 Kelvin --> 302 Kelvin No Conversion Required

What is Fouling Factor?

The water used in water-cooled condensers always contains a certain amount of minerals and other foreign materials, depending upon its source. These materials form deposits inside the condenser water tubes. This is called water fouling. The deposits insulate the tubes, reduce their heat transfer rate and restrict the water flow. The fouling factor is the reciprocal of heat transfer coefficient for the material of scale.

The following are the recommended fouling factors

1. For copper tubes used for R-12 and R-22 condensers, the fouling factor is 0.000 095 m2 s K/J.
2. For steel tubes used in ammonia condensers, the fouling factor is 0.000 18m2 s KIJ.
