A gas heated geyser consumes V_(00=1.8cm^(3) of methane (CH_(4)) in an hour. Find the temperature of the water heated by the geyser if the water flows out at the rate of v=50 cm/s. The diameter of the stream D=1cm, the initial temeprature of the water and the gas is t_(1)=11.^(@)C and teh calorific value of methane is q_(0)=13 kcal/g. The gas in the tube is under a pressure of 1.2 atm. the efficiency of the heater is eta=60% |
