Webρ = Fluid density. V = Fluid velocity. μ = Fluid viscosity. L = length or diameter of the fluid. Reynolds number formula is used to determine the velocity, diameter and viscosity of the fluid. The Kind of flow is based on the value of Re. If Re < 2000, the flow is called Laminar. If Re > 4000, the flow is called turbulent.

WebDec 16, 2013 · Calculate the force — The theoretical force output of a cylinder is the product of the air pressure applied and usable piston area exposed to it, F = P × A, where F = force in lb, P = supply pressure in psi, and A = piston area in in. 2. For example, a cylinder with a 1½-in. bore supplied with 80-psi air would generate: F = 80 × π(0.75) 2 ... WebMar 5, 2024 · Solution 10.7. The stream function for uniform flow is given by equation (7) and the stream by equation (17) (with positive sign because it is source). Hence the stream function is. (10.3.1.12) ψ = U 0 r sin θ + Q ˙ 2 π θ. For ψ = 0 equation (102) becomes. (10.3.1.13) r = − Q ˙ θ 2 π U 0 sin θ. pets purrfur
