Calculate temperature change from heat loss to ambient.

static calculate_dt(t_in, U, ml, mg, cp_l, cp_g, Atube, t_ambient)[source]

Calculate temperature change from heat loss to ambient.

Parameters:

  • t_in (float) – input pipe temperature (K)

  • U (float) – heat transfer coeff (W/m2.K)

  • ml (float) – liquid mass flowrate (kg/s)

  • mg (float) – gas mass flowrate (kg/s)

  • cp_l (float) – liquid heat capacity (J/Kg/K)

  • cp_g (float) – gas heat capacity (J/Kg/K)

  • Atube (float) – surface area (m2)

  • t_ambient (float) – ambient temperature (K)

Returns:

dT – delta pipe temperature (K)

Return type:

float
