question_answer 1)

A geyser heats water flowing at the rate of 3-0 litre per minute from 27°C to 77°C. If the geyser operates on a gas burner, what is the rate of combustion of fuel, if its heat of combustion is  

Answer:

Here, volume of water heated = litre/min., Mass of water heated,       m = 3000 g/min. Rise in temperature,          AT =77- 27 = 50°C sp. heat of water,            Amount of heat used,    Heat of combustion = Rate of combustion of fuel
