A barometer is taken to a mountain from sea level. A fall 5 cm of mercury height is observed. If average density of air is 1.30 kgm and that of mercury is 13600 kgm, calculate how high the barometer is taken. (g = 10 ms) |
| Answer» 5 CM of MERCURY height is observed.Average density of air is 1.30 kgmAverage density of mercury is 13600 kgmHeight to which the BAROMETER is taken.From the GIVEN question it is clear that fall of pressure due to mercury = Fall of pressure due to air × × g = × × g = 5/100 (m) × 13600 (kgm) × g= × 1.30 (kgm)By doing further calculation, = So, height to which barometer is taken = 523 m. | |
