nd the effort necessary is the difference of these two pres-sures. Making i? = 3 cm., this is found to be 69216 kilo-grammes. 53. A barometer is placed within a tube which is after-ds hermetically closed. At the moment of closing, theperature is 15° and the pressure 750 mm. The ax-ial space is then… … 75 V 5550/ I + 15 5550 and since in the closed space the elastic force of the air increases in the ratioI +• 30 a : I + 15 a. we shall have finally A = 30174 mm. 54. The heights of two barometers A and B have been obser%ed at — 10^ and■V 15° respectively, to be ^ = 737 and B = 763. Required their…
