Circulating Water Tunnel

Product Description

Description of DIDAC Circulating Water Tunnel: The main data concerning the Circulating Water Tunnel is as follows: Breadth of the measuring section 1.4 m Maximum water depth in the measuring section 0.84 m 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 Maximum water speed in the measuring section, approx. 5.5m/s Maximum power of the Impeller Drive 74 kW Height between middle of measuring section and middle of lower horizontal part of the circulating water channel 3.00 m Total height (not including a de-aeration container) 5.68 m 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 = 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.
