Apply the grid method (§1.7) with the hydrostatic equation (Δp = γΔz) to each of the following cases:

a. Predict the pressure change Δp in kPa for an elevation change Δz of 6.8 ft in a fluid with a density of 90 lbm/ft³.

b. Predict the pressure change in psf for a fluid with SG = 1.3 and an elevation change of 22 m.

c. Predict pressure change in inches of water for a fluid with a density of 1.2 kg/m³ and an elevation change of 2500 ft.

d. Predict the elevation change in millimeters for a fluid with SG = 1.4 that corresponds to a change in pressure of 1/6 atm.
