A small electric immersion heater is used to heat 59 g of water for a cup of instant coffee. The heater is labeled "140 watts" (it converts electrical energy to thermal energy at this rate). Calculate the time required to bring all this water from 18°C to 100°C, ignoring any heat losses. (The specific heat of water is 4186 J/kg.K.) Number i Units

Many decisions are made on the basis of the payback period: the time it will take through savings to equal the capital cost of an investment. Acceptable payback times depend upon the business or philosophy one has. For some industries, a payback period is as small as 2 yeas) Suppose you wish to install the extra insulation in the preceding problem. If energy cost $1.00 per million joules and the insulation was $4.00 per square meter, then calculate the simple payback time. Take the average T for the 120-day heating season to be 15.0 .
