SUMMARY
In pipe flow of a viscous fluid, friction and minor losses, such as those from bends and valves, lead to a reduction in total pressure, which is dissipated as heat. When dynamic pressure decreases due to reduced flow velocity, static pressure increases, but the total pressure remains constant. The heat generated from these losses is partially conducted away by the pipe and partially increases the fluid temperature. For a hose with an inner diameter of 8mm and an air pressure of 0.5 kg/cm², the flow rate can be calculated using the appropriate fluid dynamics formulas.
