The conventional friction-factor chart is not at all for the calculation of the flowrate when the available pressure gradient and the pipe diameter are known and an alternative method is developed here that facilitates calculations of this type. ...

Chart Used in Calculating Heat Pipe Thermal Resistance To calculate heat pipe thermal resistance, divide its delta-T by the power input. By choosing an 8 mm heat pipe with input power of 40oC the thermal resistance is 4.3/40 = 0.11oC/W. Additionally, the heat pipe calculator provides the ...

When the heat pipe is required to operate in orientations between -50 to -90 degrees, the wick structure can be optimized to increase the capillary pumping action. As seen in the chart below, a gravity optimized 6mm heat pipe now has a higher power carrying capacity (Qmax) than its non-...
