MR-HM 150.01 Pipe Friction for Laminar Turbulent Flow Fluids Engineering Training Equipment Didactic Equipment Vocational Training Equipment
1. Introduction to the equipment
1.1 Overview
When a fluid flows through a pipe, pressure loss occurs due to internal friction and friction between the fluid and the wall. When calculating the pressure loss, we need to know the friction coefficient, which is a dimensionless number. The friction coefficient is determined using the Reynolds number, which describes the ratio of inertial force to friction force.
MR-HM 150.01 allows you to study the relationship between the pressure loss due to fluid friction and the flow velocity in the pipe. In addition, the friction coefficient of the pipe can be determined.
The experimental setup consists of a section of small diameter pipe in which laminar-turbulent flow occurs. The Reynolds number and friction coefficient in the pipe are determined from the flow velocity and pressure loss. In the case of turbulent flow, the pipe is fed directly from the water supply system. An overflow riser ensures the constant pressure of the water supply required for laminar flow. A valve can be used to adjust the flow rate.
The pressure in laminar flow is measured by a double-tube pressure gauge. In turbulent flow, the pressure is measured by a manometer with a clock mechanism.
