WebApplication of Bernoulli's equation in open atmosphere. Example: A plane is in a level flight at a constant speed and each of its two wings has an area of 25 m 2. If the speed of air is 180 km h −1 over the lower wing and 234 km h −1 over the upper wing surface, the plane's mass is. (Take density of air = 1 kg m −3 .) WebOct 25, 2024 · Bernoulli’s Principle Formula. Bernoulli’s principle can be mathematically expressed as, p 1 + 1 2 ρ v 1 2 + ρ g y 1 = p 2 + 1 2 ρ v 2 2 + ρ g y 2. or, It can also be expressed as, P + ρ g h + 1 2 ρ v 2 = Constant. This is referred to as Bernoulli’s Equation. Here, ρ = Density of the fluid. v 1 = speed of liquid at point A 1.
