Circulating Water Tunnel

Product Description

Description of DIDAC Circulating Water Tunnel:

The main data concerning the Circulating Water Tunnel is as follows:

1. Breadth of the measuring section 1.4 m
2. Maximum water depth in the measuring section  0.84 m
3. The false floor of the measuring section can be shifted in height so that the water depth can be reduced down to  0.02 m
4. Maximum water speed in the measuring section, approx.  5.5m/s
5. Maximum power of the Impeller Drive  74 kW
6. Height between middle of measuring section and middle of lower horizontal part of the circulating water channel 3.00 m
7. Total height (not including a de-aeration container)  5.68 m
8. Total length 16.18 m

Technical Data of DIDAC Circulating Water Tunnel:

The circulating water channel is designed for lower and medium speeds. The design permits the manufacture and operation of a channel with a relatively large measuring section at still moderate cost. The pressure above the water surface can be reduced to slightly above vapour pressure. So the Cavitation numbers below Æ = 0.1 can be reached at the water surface in the measuring section. Due to the moderate water speed, the cavitation number is quickly increased with water depth.
