Description:
The Friction Loss in a Pipe Apparatus is designed to measure friction loss in a horizontal pipe and to facilitate the study of laminar and turbulent flow. This apparatus offers precise control and measurement for investigating the transition between laminar and turbulent flow, allowing for the determination of the critical Reynolds number and verification of Poiseuille's equation for laminar flow.
Key Features:
• Small-bore Straight Test Pipe: Mounted on a stable base plate, ideal for measuring friction loss in a horizontal pipe.
• Direct Measurement of Friction Loss: Enables precise analysis of friction loss within the small-bore test pipe.
• Laminar and Turbulent Flow Investigation: Facilitates the study of flow dynamics, including the transition point between laminar and turbulent flow regimes.
• Critical Reynolds Number Display: Allows for the observation of the critical Reynolds number for flow regime changes.
• Poiseuille’s Equation Verification: Enables verification of Poiseuille’s equation and determination of water viscosity in the laminar flow region.
• Precision Valve: Provides accurate flow control to ensure precise experimental conditions.
• Header Tank for Laminar Flow: Ensures consistent laminar flow conditions for accurate measurements.

Experiments to be Performed:
• Investigation of laminar and turbulent flow characteristics.
• Measurement of the change in resistance (friction factor) as flow transitions from laminar to turbulent.
• Determination of the critical Reynolds number.
• Verification of Poiseuille’s equation and calculation of the coefficient of viscosity for water in the laminar flow region.
