question 63

Multiple Choice

Follow the rules for working with measurements. The pressure at the bottom of a lake is found by the formula P = hD, where h is the depth of the water and D is the density of the water. Find the pressure in $1 \mathrm {~b} / \mathrm { in } ^ { 2 }$ at 250 ft below the surface. $D = 62.41 \mathrm {~b} / \mathrm { ft } ^ { 3 }$ .

• A) \(P = 1,3001 \mathrm {~b} / \mathrm { in } ^ { 2 }\)
• B) \(P = 1101 \mathrm {~b} / \mathrm { in } ^ { 2 }\)
• C) \(P = 650 \mathrm { lb } / \mathrm { in } ^ { 2 }\)
• D) \(P = 2171 \mathrm {~b} / \mathrm { in } ^ { 2 }\)
• E) \(P = 1081 \mathrm {~b} / \mathrm { in } ^ { 2 }\)
