The gauge pressure in a balloon in measured by means of an open-tube manometer that uses water (density=1.00×10^3 kg/m3). What gauge pressure p is indicated by a difference of 0.0139 m in the heights of the water columns?
Homework Answers
difference in height , h = 0.0139 m
density of water, p = 1000 Kg/m^3
for the difference in pressure
difference in pressure = pgh
difference in pressure = 1000 * 9.8 * 0.0139
difference in pressure = 136.2 Pa
the difference in pressure is 136.2 Pa
