Pressure drop and heat loss parameter are required when designing pipe system and determining separator location. The calculation of pressure drop and heat loss is complex and time-consuming when manually calculated. Therefore, this paper explains about software interface to create a model and simulation of thermal heat loss and pressure drop calc ulations on the pipe system. For the condition of one phase fluid, we will use the Homogeneous method, while the condition of two-phase fluid, Beggs-Brill, Harrison-Freeston, or Zhao-Freeston methods will be used. This software has been validated using a serie s of pipes in Wayang Windu Geothermal Field (WWQ-3). WWQ-3 has wellhead pressure 12,7 bar-a, enthalpy 2745 kJ/kg, total ma ss flow 9,6 kg/s and 14 data pipe fitting. The result of total heat loss is 8,14 kW and the total pressure loss is 0,13 bar-a with Harris on-Freeston method, 0,12 bar-a with Zhao-Freeston method, and 0,19 bar-a with Beggs-Brill method. All of those methods get l ess than 1% error, with Beggs-Brill method giving the best estimation. Comparison between model and data complies with the expected minimum error, so the model is considered to be valid and can be used for simulation.
