Document Summary
Latent heat is the heat energy in an air stream due to the moisture of the air. An airstream of 800f/60% rh (relative humidity) has more latent heat than an airstream of 800f/50% rh. Viscoelastic food behaviour means that some foods are composed of both viscous and elastic materials, and in addition, they exhibit both flow and deformation: a plastic solid behaves differently when under the influence of shear stress. A newtonian fluid represents an ideal fluid whose viscosity and flow characteristics are readily predictable. Behaviour of non-newtonian fluids is not as simple to predict: shear thinning fluids are said to exhibit pseudoplastic behaviour. What this means is that the viscosity of the fluid decreases (becomes thinner) as shear rate increases (yogurt). Shear thickening fluids are said to exhibit dilatants behaviour.
