water at temperature 20c flows from a tap t into a container c at the rate of 0021 litre per min

Step 1: Calculate the rate of heat transfer using the formula p = ρsΔT + ρl, where ρ is the dens

Question

Water at a temperature of 20°C flows from a tap T into a container C at a rate of 0.021 liters per minute. The heating element (resistor R) generates sufficient power P so that the water in the container boils and gets converted into steam. At steady state, it is found that the amount of water in the container neither increases nor decreases with time. Neglecting heat losses, the value of P (in W) is given by (to the nearest integer) [For water specific heat capacity = 4.2 kJ/kg K; latent heat of vaporization = 2.3 MJ/kg]
