Trying to move 26.4gpm through a full 3 / 4in inside diameter hose you will have about 60psi friction loss per 100 feet of length.
22.
Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation and industrial equipment, have a physical or engineering basis.
23.
For example, a motorcycle's wheels are placed in contact with a set of rollers which can be adjusted to simulate friction losses and aerodynamic resistance.
24.
Note that the friction loss is insensitive to the pipe roughness height : the flow velocity in the neighborhood of the pipe wall is zero.
25.
This and heat and friction losses are influences that can be included in the Hertzian equations to make them more general and for subsequent collisions.
26.
Curtiss-Wright showed also that the rotor can be widened, keeping the rest of engine's architecture unchanged, thus reducing friction losses and increasing displacement and power output.
27.
Stiffer valve springs can help prevent valve float and valve bounce, but only at the expense of increased friction losses and higher stresses in the valvetrain.
28.
So unless the engine is run at very low rotational speeds, the friction losses due to centrifugal forces acting on the piston assemblies can quickly become unacceptable.
29.
The 2.2-litre, 4-cylinder engine features a pent-roof combustion chamber configuration and reduced friction loss from moving parts, which results in excellent combustion efficiency and low fuel consumption.
30.
The primary drawback to the revolving cylinder, axial piston engine design is that rotating piston assemblies are subjected to centrifugal forces, which can result in significant friction losses.
