I just started to fabricate my own water tunnel. Plan is to make the tunnel so big that you can test 1:24 truck.

Truck main dimensions are 100mm (W) x 150mm (H) Tunnel dimensions will be 5x those -->500x750mm.

Trucks length is about 700mm
What is enough length for this tunnel?
Is that turn too tigth?

All pictures, datasheets and videos of working water tunnels are welcome. There will be huge acryl window to see the test sections flow properly
