Step-by-step explanation:
To find the fluid pressure in psi using the formula P = Dh, where D is the fluid density and h is the height of the fluid column, we need to first convert the density units to lb/ft^3 to match the units of the other variables.
Given:
d = 62.4 lb/ft^3 (fluid density)
h = 150 feet (height of fluid column)
We can substitute the given values into the formula to get:
P = Dh = (62.4 lb/ft^3) x (150 feet)
To get the pressure in psi, we need to convert the units of the result to pounds per square inch (psi). Since 1 psi is equivalent to 144 square inches (in^2), we can divide the result by 144 in^2 to get the pressure in psi:
P = (62.4 lb/ft^3) x (150 feet) / 144 in^2/ft^2
Simplifying, we get:
P = 65 psi (rounded to the nearest whole number)
Therefore, the fluid pressure in psi is 65 psi.
