Quick Answer: Kaplan Turbine Test Setup is an axial flow reaction turbine rig for low heads, used to study turbine operation and determine output power and efficiency. It is offered in 1.33 HP and 5 HP versions, each with a scroll casing, guide vanes, a runner with adjustable vanes and a draught tube.

About This Product
Because the power produced is proportional to QH, a low-head turbine like this needs a larger discharge to give the same power, which the HYDRAULIC MACHINE LAB set-up supplies from its centrifugal pump. Loading the runner through the brake arrangement and reading the inlet and outlet gauges gives the data for output power and turbine efficiency.
Frequently Asked Questions
Q1. Where can the flow onto the vanes be seen? Through a transparent hollow acrylic cylinder fitted between the draught tube and the casing.
Q2. What head does the turbine work at? It is suited to low heads; both versions are listed with a supply head of 5 m.
