Helical coils are used for heating or cooling in process tanks. When a fluid flow through a curved tube, centrifugal force acting upon the various elements of fluid moving with different velocities causes secondary circulation. Secondary flow results in higher heat transfer characteristics. Further secondary flow stabilizes the laminar flow leading of a higher critical Reynolds number for transition from laminar to turbulent flow.

Experiments

• To determine the critical Reynolds number of a fluid flowing through the coil.
• To determine the friction factor for flow of water through helical coil
• To compare the pressure drop in helical coil with that in a straight pipe of same length, inside diameter and surface roughness

Utilities Required

• Electricity 500 watts, 220 V, 1 phase
• Floor area 1 m x 2 m

The apparatus has been designed to introduce students to the fundamental characteristics of the behavior of the particle system, in particulars the relationship between the drag coefficient of falling particles and their Reynolds number value. Particles covering a range of sizes and densities are supplied and the experiments are conducted by allowing single particles to fall through a number of different liquids contained in vertical glass tube. The rate of fall of the particle is determined by timing their passage between two marks on the walls of the glass tubes. Observation of particle movement is aided by the provision of a shielded fluorescent tube light mounted on the backboard. Particles can be removed from the bottom of the tubes without the necessity of draining the liquid. A valve system is provided at the bottom of each tube to allow the particles to be removed with the minimum loss of liquid.

Experiments

• To measure the drag co-efficient
• To plot the graph between drag co-efficient vs. Modified Reynolds number
• To study the motion of a solid particle through a liquid

Utilities Required

• Electricity supply 100 watts, 220 , 1 phase
• Floor Area 0.75 m x 1.5 m
• Liquids of different viscosity
