sure-ments of the weight and temperature of the condensed steam,the heat entering from measurements of pressure, quality, andweight by methods already explained. The heat taken up bythe air is the difference of that entering and discharged. If anelectric heater is used, the electric energy… … Fig. 329.—Diagram of Method of Measuring Velocity of Air. The temperature of the entering and discharge air shouldbe taken at sufficiently numerous points in the cross-section tomake the average results accurate, and the thermometers shouldbe protected from radiant heat. The average temperature…
