Final answer:
To calculate the point velocity from given pressure in psi, Bernoulli's principle is used, where the initial pressure P₁ is related to the fluid density and the velocity at another point in the system, and requires conversion from psi to consistent units.
Step-by-step explanation:
The question asks to provide the point velocity given the pressure in psi. To calculate this, we can use Bernoulli's principle, which relates pressure with fluid velocity.
According to Bernoulli's principle, P₁ + ½ pv² = P₂ + ½ pu. If we assume that one point in the flow has a pressure P₁ and zero velocity (v₁ = 0), then the velocity at another point (v₂) can be calculated using P₂ and the density of the fluid (p).
Using the given initial pressure P₁ (in psi that needs to be converted to N/m² or Pa for consistency) and assuming that we know the fluid density p, we can rearrange the equation to find the point velocity (v₂) as: v₂ = √((2(P₁ - P₂)) / p), where P₂ could be the atmospheric pressure or another known pressure in the system.
