What is Critical Velocity.????

Answer 1

✌❤Critical Velocity❤✌

• ✌❤The critical velocity is that velocity of liquid flow, below which its fl is streamlined and above which it becomes turbulent.❤✌

• ✌❤Critical velocity vc = (kη/rρ)❤✌

• ✔where,✔

• ❤✌K = Reynold’s number,❤✌
• ✌❤η = coefficient of viscosity of liquid❤✌
• ✌❤r = radius of capillary tube and ρ = density of the liquid.❤✌
