Boundary Layer, Viscosity, VelocityAbstract
The boundary layer is a boundary layer formed due to friction between the cross-sectional surface and the fluid, resulting in a velocity gradient. This study observes the fluid velocity gradient in the boundary layer in a straight pipe using an experimental method. The fluid velocity distribution was measured using a 1” diameter acrylic pipe and a 1.5 mm diameter blunt needle that resembles a pitot tube with a system of stagnation pressure and static pressure differences. Fluids with various viscosities and flow rates were tested to understand their effects on the characteristics of the boundary layer. With a flowrate of 10 liters/minute shows that the results of fluid velocity measurements increase with increasing radial distance on the pipe wall starting from =2 mm (0,334 m/s), =5,5 mm (0,341 m/s), =7,5 mm (0,425 m/s), =10,5 mm (0,438 m/s), dan pada =12,7mm (0,443 m/s).
