What is Fluid Mechanics?

Fluid dynamics is “the branch of applied science that is concerned with the movement of liquids and gases”. It involves a wide range of applications such as calculating force & moments, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space, and modelling fission weapon detonation.

What are the Applications of Fluid Dynamics?

Fluid Dynamics can be applied in the following ways: Fluid dynamics is used to calculate the forces acting upon the aeroplane. It is used to find the flow rates of material such as petroleum from pipelines. It can also be used in traffic engineering (traffic treated as continuous liquid flow).

How to Calculate Wetted Surface Area?

Wetted Surface Area calculator uses Wetted Surface Area = 2*pi*Radius of Inner Cylinder*Length of Cylinder to calculate the Wetted Surface Area, The Wetted Surface Area formula is a function of radius of inner cylinder and length of cylinder. In maritime use, the wetted area is the area of the hull which is immersed in water. This has a direct relationship on the overall hydrodynamic drag of the ship or submarine. Literally how much of the pipe cross-section is “wet” or in contact with the fluid. Let’s say you have a very large sewer pipe under the road. The “wetted” area is only a small portion at the bottom and it should only be fairly full in cases of heavy rain. Now, in a siphon, in which the pipe has to be “primed” so that continuity of flow will make the fluid go from high to lower hydraulic grade, the entire cross-section of the pipe is wetted (ie, in contact with the fluid) or else it doesn’t maintain the siphon. Wetted Surface Area is denoted by A_w symbol.

How to calculate Wetted Surface Area using this online calculator? To use this online calculator for Wetted Surface Area, enter Radius of Inner Cylinder (R) & Length of Cylinder (L_Cylinder) and hit the calculate button. Here is how the Wetted Surface Area calculation can be explained with given input values -> 0.150796 = 2*pi*0.06*0.4.
