It tasted stale right out of the microwave, and only continued to shrivel up as it cooled. Not only did this method leave behind many un-popped kernels, the popcorn also easily burned if left in the microwave for just seconds too long.
WebFeb 3, 2024 · The Biot number, (Bi = hV/kA), is a ratio of the internal (conductive) resistance to heat transfer, to the external (convective) resistance to heat transfer. A general rule of thumb is that a body can be assumed to be lumped if Bi < 0. 1 (Welty1). For lumped bodies, the temperature variation with time is described by Equation 6 (Welty1) For ...
