In an experimental set-up, 5 kg of salt solution is heated in a glass vessel by a gas burner. An electric stirrer is used to ensure uniform heating of the solution. The internal energy of the solution is to be increased from 200 to 250 KJ/kg in 15 minutes. The power consumption of the stirrer is 30 W. The rate of heat loss from the vessel is 50W. Determine the power of the gas burner required.
