Question

PHYSICS The pressure exerted on an object is calculated by the formula P=FA, where P is the pressure, F is the force, and A is the surface area of the object. Water shooting from a hose has a pressure of 75 pounds per square inch (psi). Suppose the surface area covered by the direct hose spray is 0.442 square inch. Solve the equation for F and find the force of the spray. pounds

Answer 1

To solve for the force (F) of the spray, we can rearrange the formula P = FA to isolate F:

P = FA

We know that P = 75 psi (pressure) and A = 0.442 sq in (surface area), so we can substitute these values into the equation:

F = PA

F = (75 psi) x (0.442 sq in)

F = 33.98 N

Therefore, the force of the spray is approximately 33.98 Newtons (N).

The above answer is based on the formula P = FA, where P is the pressure, F is the force, and A is the surface area of the object. The surface area of the object in this case is 0.442 square inch, and the pressure is 75 pounds per square inch (psi). By rearranging the formula, we can solve for the force of the spray, which is approximately 33.98 Newtons (N).
