During very cold weather conditions, cricket players prefer to wear white woolen sweaters rather than colored woolen sweaters. The reason is that white wool comparatively: 1. Absorbs less heat from the body 2. Emits less heat to the atmosphere Which of the above statements is/are correct?
Statement 1: Drying is used for preservation of food. Statement 2: Convective drying is indirect drying and conductive drying is direct drying.
A solid is being dried in the linear drying rate regime from moisture content Xo to XF. The drying rate is zero at X = 0 and the critical moisture content is the same as the initial moisture Xo. The drying time for M = (Ls/ARc) is (where, L = total mass of dry solid, A = total surface area for drying Rc = Constant maximum drying rate per unit area X = moisture content (in mass of water/mass of dry solids)
200 kg of solids (on dry basis) is subjected to a drying process for a period of 5000 seconds. The drying occurs in the constant rate period with the drying rate as, Nc = 0.5 × 10-3 kg/m2.s. The initial moisture content of the solid is 0.2 kg moisture/kg dry solid. The interfacial area available for drying is 4 m2/1000 kg of dry solid. The moisture content at the end of the drying period is (in kg moisture/kg dry solid)
