Calculate the drag force acting on a moving vehicle with a frontal area of 6m² and a velocity of 30 m/s, considering a drag coefficient of 0.3 and air density of 1.225 kg/m³.
💡 Hint: Be sure to square the velocity before applying it to the formula.
Analyze a fluid system where inertia forces are more significant than viscous forces. How would the flow regime be categorized at a Reynolds number greater than 4000?
💡 Hint: Consider the value of the Reynolds number and its relation to flow type.
