5.2 Расчетная часть

Рассчитываем приход тепла:

Q₁=F*C_f*t^f                                                                                                        (5.1)

Q₁= 2*1764.8*65.3=230.48 Bт

C_f = C_н.к*a_f +C_в.к *(1- a_f)                                                                                  (5.2)

С_f­ =900*0.6243200*(1-0.624)=1764.8  Дж/кг*К

Q₂= Ф*С_ф*t_ф                                                                                                   (5.3)

Q₂= 0.3875*1429*54=29901.825  Вт

С_ф= C_н.к*a_p +C_в.к *(1- a_p)                                                                                 (5.4)

С_ф= 900*0.77+3200*(1-0.77)=1429  Дж/кг*К

t_ф= 64-10= 54 ⁰С

Рассчитаем расход тепла:

Q₃ =G*J_p                                                                                                          (5.5)

а_н.к.=а_р                                                                                                              (5.6)

r_p=r_н.к+a_p+r_в.к.*(1- a_p)                                                                                       (5.7)

r_p=0.0000193*0.77*0.0000108*(1-0.77)=0.0000174 Дж/кг

I_p= r_p+C_p*t_p                                                                                                       (5.8)

I_p =0.0000174+1429*64=91456  Дж/кг

Q₃=W*C_w*t_w;  Q₃=1.16*91456=106088 Вт                                                    (5.9)
