The entry of water in Perspex tube is through elliptical bell mouth to have smooth flow at the entry. A regulating valve is provided on the downstream side of the tube to regulate the flow. A collecting tank is used to find the actual discharge through the Perspex tube. The discharge must be varied very gradually from a smaller to larger value.

Apparatus consist of storage cum supply tank, which has the provision for supplying coloured dye through jet. A Perspex tube is provided to visualize the different flow condition. 

Specification:-

•  Flow control valve to change Discharge.

•  Transparent pizometer tubes with scale to measure head.

•  Acrylic tube of Dia.25mm and length 1 mtr. to study different flow conditions.

•  1 Litter plastic flask to measure discharge.

•  Sump tank- 900 X 350 X 350 mm.

Range of Experiment:-

•  To obtain the Reynolds number in different flow conditions.

•  To study different flow conditions.
