Heat
a. Calculate the time required for an
electric water heater to raise
temperature of 10 litres of water
from 15°C to 65°C, if the heating
element takes a current of 10A from
a 240V supply and the efficiency of
the heating process is 80%. Take
specific heat capacity of water to be
4180J/Kg and 1kg of water as 1 litre.
