The average latent heat of evaporation of water is 2.3 mj/kg at 25oc-160oc. the heating value of a biomass material is 17 mj/kg on a dry basis. if the moisture content of the biomass is 50% on a wet basis, what percentage of the total energy stored in the biomass is required to remove all water in the biomass during gasification?

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
