m as in the pipe b, sincethe velocity of the steam will affect thegauge-reading, making it less than thereal pressure. The reservoir is wrappedwith hair-felt and lagged with wood to reduce radiation ofheat. When a test is to be made, the valve on the pipe d isopened wide (this valve is frequently… … Fig. 69. TESTING STEAM-ENGINES. 295 It is well to wait about ten minutes after the instrument isstarted before taking readings so that it may be well heated.Let the boiler-pressure be /, and let r and q be the latentheat and heat of the liquid corresponding. Let p1 be thepressure in the…
