Mass flow inlet:

qm = qV · ϱM = 0,00133 m³/s · 869,9 kg/m³ = 1,16 kg/s

Specific heat capacity of the pure substances (p. 110/111)

cpB = 1740 J/(kg · K) cpT = 1710 J/(kg · K)

Specific heat capacity of the mixture (p. 79)

cM = wB · cpB + wT · cpT = 0,25 · 1740 J/(kg · K) + 0,75 · 1710 J/(kg · K) = 1717,5 J/(kg · K)

Conversion of electrical energy into thermal energy (p. 91):

Required electrical power: P = 173974,2 W
