4 medida viscosidad

2.3 Medida de la viscosidad

La viscosidad de un lquido puede medirse utilizando diferentes mtodos. Los instrumentos ms comunes son el viscosmetro de tubo capilar y el rotatorio.

2.3.1 Viscosmetro de tubo capilarFig. 2.8. Balance de fuerzas de seccin en un tubo capilar.

La presin (P) es fuerza por unidad de rea, donde el rea corresponde a la de la seccin transversal. Entonces: La presin (P) es suficiente para vencer las fuerzas de cizalla dentro del lquido y produce un flujo a una velocidad determinada. Las fuerzas de cizalla operan en la superficie interna del lquido a lo largo de toda la longitud L del tubo y a una distancia r del centro del tubo. La fuerza de cizalla es fuerza por unidad de rea, donde el rea es la de seccin circular; entonces:(2.4)(2.5)

(2.6)(2.7) Entonces:De la ecuacin (2.7) es evidente que la fuerza de cizalla o esfuerzo cortante variar desde cero en el centro del tubo hasta PR/2L en la pared del tubo (donde r = R).Combinando la ecuacin (2.1) y la (2.7)

Separando variables:(2.8) (2.9)

Integrando desde la pared del tubo R donde u = 0 hasta cualquier posicin r donde la velocidad local es u entonces: (2.10)

La ecuacin (2.11) es una expresin que define el perfil de velocidad de tal manera que, para un lquido de viscosidad , la velocidad del mismo ser u en un punto r cuando exista una cada de presin P a lo largo de un tubo de longitud L.

El rea de la seccin transversal de una capa dentro del tubo (Fig. 2.8) puede expresarse como(2.12)(2.11)

Entonces, el volumen del lquido que fluye en la capa por unidad de tiempo (es decir, el caudal volumtrico) corresponde a la velocidad u multiplicada por el rea dA (2.13)Integrando desde el centro del tubo (r = 0) hasta la pared del mismo (r = R), y sustituyendo la velocidad u obtenida de la ecuacin (2.11). (2.14)

(2.15)

La ecuacin (2.15) es la base del diseo y operacin de cualquier viscosmetro de tubo capilar. Para un tubo de longitud L y radio R, la medida de un caudal a una presin P permitir determinar la viscosidad . (2.16) Como la ecuacin (2.16) est basada en las caractersticas propias de un fluido newtoniano, cualquier combinacin caudal-cada de presin dar el mismo valor de viscosidad.

La ecuacin (2.15) es tambin vlida para determinar el caudal en una tubera circular cuando se conocen sus dimensiones (radio y longitud), la viscosidad del lquido y la cada de presin a lo largo de la tubera.

Si la fuerza de la gravedad es la responsable de la presin necesaria para el flujo del fluido, tal como ocurre en un tubo capilar, puede utilizarse una variante del desarrollo matemtico anteriormente utilizado para el viscosmetro de tubo capilar. Considerando que: (2.18) entonces, la ecuacin (2.16) se transforma en:

(2.19)

(2.17)

Teniendo en cuenta que las medidas de viscosidad son funcin del tiempo necesario para que el lquido fluya a travs del tubo capilar, y que el volumen del tubo cilndrico es V = .R2.L y la masa = V. (volumen x densidad), se obtiene que: La medida de la viscosidad de un lquido en un tubo capilar ser funcin de la masa m de lquido existente en el tubo, la aceleracin de la gravedad (g = 9.8 m/s2), y la longitud del tubo L. La viscosidad puede determinarse midiendo el tiempo que tarda en vaciarse el lquido existente en el tubo.(2.20)

2.3.2 Viscosmetro rotatorio

Para calcular la viscosidad debe conocerse la relacin entre el par de torsin, , y el esfuerzo cortante, , as como las revoluciones por segundo, N, y la velocidad de cizallamiento, .:Fig.2.9.Esquema de un viscosmetro rotatorio de cilindros coaxiales. (2.21)

Sustituyendo estas relaciones en,(2.22)La velocidad de cizalla, es funcin de la velocidad angular . (2.23)

Donde el cilindro exterior (RO) es estacionario (=0) y el interior (Ri) tiene una velocidad angular (= i ). La integracin conduce a:

(2.25) (2.24)

Teniendo en cuenta que: Entonces: (2.26) (2.27)Una variante del viscosmetro coaxial-cilndrico es el viscosmetro de cilindro simple en el que un nico cilindro de radio Ri, se sumerge en un recipiente con la muestra. En este caso, el radio del cilindro exterior Ro puede considerarse infinito, y la ecuacin (2.27) se transforma en:(2.28)

2.3.3Influencia de la temperatura en la viscosidadla sensibilidad de la viscosidad respecto de la temperatura es del 3 %/C a temperatura ambiente. Esto significa que para obtener una precisin en la medida de 1% se requiere que la temperatura de la muestra se mantenga dentro de 0.3C.

Existen evidencias que demuestran que la influencia de la temperatura sobre la viscosidad para los alimentos lquidos puede describirse mediante una relacin tipo Arrhenius(2.29)

EXPERIENCIAS EN LA DETERMINACIN DE CARACTERSTICAS REOLGICAS DE PRODUCTOS AGROALIMENTARIOS DE VISCOSIDAD MEDIA

La mayor parte de las operaciones bsicas de la industria alimentaria, tanto en la conservacin como en el procesado de alimentos, conllevan al manejo de fludos en movimiento.

La propiedad ms importante que rige el flujo de un fludo es su consistencia, ya que determina la resistencia que hay que vencer para conseguir su desplazamiento.

La consistencia de un alimento es una propiedad no solo esencial en Ingeniera de Procesos para el clculo y diseo de las correspondientes operaciones, sino que es de inters en otras aplicaciones como son el control de calidad, la evaluacin sensorial y la determinacin de la estructura microscpica de los alimentos

OBJETIVOS: Evaluar el efecto de seis proporciones semilla/agua (1/10, 1/12, 1/14, 1/16, 1/18, 1/20), siete temperaturas (60, 65, 70, 75,80, 85, 90C), seis tiempos (50, 60, 70, 80, 90, 100 min) en el rendimiento de extraccin, caractersticas reolgicas y fisicoqumicas de goma de semilla de tara. Determinar la proporcin semilla/agua, temperatura y tiempo para obtener el mejor rendimiento de extraccin de goma de semilla de tara. Comparar extracciones hidrotrmicas, con cidos clorhdrico (0.1%), ascrbico (0.1%).
