Concept

Problem: Assume Patmos=1.00atm. What is the gas pressure in the manometer Pgas? Express your answer in pascals to three significant figures.h1 = 13.5 cmh2 = 6.00 cmDensity of mercury = 1.36×104 kg/m3

FREE Expert Solution

1 Pa=1 N/m2

Pgas=Patmos+(h2-h1)ρg

h1 = 13.5 cm (1 m / 100 cm) = 0.135 m

h2 = 6.00 cm (1 m / 100 cm) = 0.06 m

ρ = 1.36×104 kg/m3

g = 9.8 m/s2
