During flow through pipes, pressure losses occur due to internal friction and friction between
the fluid and the wall. When calculating pressure losses, we need to know the friction factor,
a dimensionless number. The friction factor is determined with the aid of the Reynolds
number, which describes the ratio of inertia forces to friction forces. SMT-FM-08 enables the
study of the relationship between pressure loss due to fluid friction and velocity in the pipe
flow. Additionally, the pipe friction factor is determined. The experimental unit includes a
small diameter pipe section in which the laminar and turbulent flow is generated. The
Reynolds number and the pipe friction factor are determined from the flow rate and pressure
loss. In turbulent flow, the pipe is supplied directly from the water supply. The constant
pressure at the water supply required for laminar flow is provided by a standpipe on the
overflow. Valves can be used to adjust the flow rate.
