A FLAT WALL OF A 6 m OVEN, WHERE BREAD IS PRODUCED, IS COMPOSED OF 10 cm OF HOLLOW BRICK, INSULATED BY A 5 cm
A FLAT WALL OF A 6 m OVEN, WHERE BREAD IS PRODUCED, IS COMPOSED OF 10 cm OF HOLLOW BRICK, INSULATED BY A 5 cm LAYER OF FIBERGLASS ON THE EXTERIOR. CALCULATE: a).- THE TEMPERATURE LOSSES INSIDE THE OVEN IS 100 C, WHILE THAT OF THE I
HEAT (HEAT FLUX) IN Kcal /hr, b). THE DISTRIBUTION OF TEMPERATURES IN THE WALL, AND c).-PLACE THE GRAPH OF THEM (L -vs- T). THE
OUTSIDE WALL IS 20 C.
THE THERMAL CONDUCTIVITIES ARE:
Klad = .49 Kcal/hr-m-C
Kfv=.035 Kcal/hr-m-C
PROBLEMA 1 DL TAREA DE CONDUCCIN DE CALOR UNA PARED PLANA DE UN HORNO DE 6m2, DONDE SE PRODUCE PAN, EST COMPUESTA POR 10cm DE LADRILLO HUECO, AISLADA POR UNA CAPA DE 5cm DE FIBRA DE VIDRIO POR EL, EXTERIOR. CALCUI.AR: a).- LAS PRDIDAS DE CALOR (FLUJO DE CALOR) EN Kcal/hr, b).-LA DISTRIBUCIN DE TEMPERATURAS EN LA PARED, Y c). -TRAZAR LA GRFICA DE ELLAS (L -vs- T). LA TEMPERATURA INTERIOR DEL HORNO ES DE 100C, MIENTRAS QUE LA DE LA PARED EXTERIOR ES DE 20C. LAS CONDUCTIVIDADES TRMICAS SON: Klad=.49Kcal/hrmC Kfv=.035Kcal/hrm9oC
