Q. 3. Water is boiled at sea level ( 1 atm pressure) and thus at a saturation (or boiling) temperature of Tsat =100 degree Celsius by a copper heating element. The surface temperature of the heating element is to be determined. The initial temperature of the water is 18 degrees (1L). Once boiling starts, half of the water vapourizes in 25 minutes. How long will it take for this heater to raise the temperature of 1L water from 18 degrees to boiling temperature? lvPrl=957.9kg/m3=0.60kg/m3=0.0589N/m=1.75D=4cmL0cmhf/glCpl=2257103J/kg=0282103kgm/s=4217J/kgC
