This is a kinematic viscosity problem. There is a simple formula for the force; see link below.Abigail1997 said:
Power lost due to friction in a propeller refers to the energy that is dissipated or wasted as a result of the propeller's interaction with the surrounding fluid medium, such as air or water. This energy is lost in the form of heat and vibrations, ultimately reducing the overall efficiency of the propeller.
Friction has a significant impact on the performance of a propeller. As the propeller blades move through the fluid medium, they experience resistance and drag due to friction, which reduces the amount of power that can be converted into thrust. This results in a decrease in the propeller's efficiency and overall performance.
Several factors contribute to power loss due to friction in a propeller. These include the roughness of the propeller's surface, the viscosity of the fluid medium, the shape and size of the propeller blades, and the speed at which the propeller is rotating.
To minimize power loss due to friction in a propeller, the design and construction of the propeller should be carefully considered. Using smooth and streamlined propeller blades, reducing the roughness of the propeller's surface, and optimizing the size and shape of the blades can all help to reduce friction and improve efficiency.
No, it is not possible to completely eliminate power loss due to friction in a propeller. However, through careful design and maintenance, it is possible to minimize the effects of friction and improve the overall efficiency of the propeller.
