Displaystyle frac partial u partial tDelta u. C p 4180 x w 1711 x p 1928 x f 1547 x c 0908 x a is the equation used for finding the specific heat of foods where w is the percentage of the food that is water p is the percentage of the food that is protein f is the percentage of the food that is fat c is the percentage of the food that is carbohydrate. The bar is uniform the heat equation becomes u t k2u Q cp 6 6 u t k 2 u Q c p where we divided both sides by cr c r to get the thermal diffusivity k k in front of the Laplacian.
Q heat energy Joules J.
C Q m x DT Q supplied or subtracted heat in joules M the samples mass DT initial and final temperature difference J kgK heat capacity measurement type Specific Heat Values The heat capacity calculator is going to be useful in many situations. C p 4180 x w 1711 x p 1928 x f 1547 x c 0908 x a is the equation used for finding the specific heat of foods where w is the percentage of the food that is water p is the percentage of the food that is protein f is the percentage of the food that is fat c is the percentage of the food that is carbohydrate. The formula for heat capacity is below. Xx ignoring the initial and boundary conditions for the moment.
