Question:

As shown, gas at pressure p_g raises a column of liquid to a height h. The gage pressure in the gas is given by pg = γ_liquidh. Apply the grid method (§1.7) to each situation that follows.

a. The manometer uses a liquid with SG = 1.4. Calculate pressure in psia for h = 2.3 ft.

b. The manometer uses mercury. Calculate the column rise in mm for a gage pressure of 0.5 atm.

c. The liquid has a density of 22 lbm/ft ³. Calculate pressure in psfg for h = 6 inches.

d. The liquid has a density of 800 kg/m³. Calculate the gage pressure in bar for h = 2.3 m.
