Thenceit passes into another small reservoir J, from which it is conductedthrough an india-rubber tube into measuring flasks. There is athermometer at F to measure the temperature of the waterentering, and another at H to measure the temperature of thewater leaving the calorimeter. The hot gases from the Bunsenburner B pass up inside the calorimeter to the top K, where theyare deflected down through tubes L L passing through the waterinto a small chamber M at the bottom. Thence they pass into theatmosphere through flue N. The water produced by the combustionis drained off at 0 and carefully measured. 155 SUCTION GAS Fig. 35.—Junkers Calorimeter for testing Calorific Value of Gas. APPENDICES. 157 The following account of a series of tests made to determine thecalorific value of coal gas by the use of this apparatus will helpto make the method of conducting such tests and working out theresults more clear. The pressure and temperature of the gas at inlet and outlet
